tough to answer, but if slope is only provided then it should intercept at (0,0). Such as, y=3x, that intercepts at 0.

Describe a situation in which point-slope form would be more useful than slope-intercept form?
You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
How do you find the x-intercept of a line?
On one of my projects for my algebra class...my professor is asking us to find the slope of a line which is fairly easy.....but i only have one point and it's impossible to find a slope with only one point....what am i doing wrong?

Has y intercept 8 and slope 0?
Yes, it is possible only when the x-intercept is infinite. so slope=y/x = 0.
The slope of a line is -3. Find the slope of a line that is perpendicular to this line. The slope of a line is -3.?
The slope of two lines are perpendicular only if their slopes multiplied together equal -1 (m1*m2 = -1). So if a line has a slope of -3 then a line perpendicular to this one has a slope of -1/-3 or 1/3.
How do you find the slope intercept and standard forms of a line when the slope is undefined and you are given the coordinates 2 and 4?
When the slope is undefined, you know the line has to be vertical. Vertical lines only have an x in their equations. When you have the coordinates (2,4) with a vertical line, the equation for the slope intercept AND standard form would be the same thing: x=2

When creating a line using the slope-intercept form always plot atleast three?
In the case that you are using Slope-Intercept Form, no, you only plot two points: the y-intercept and one other point. If you don't use Slope-Intercept Form, then you have to use three points.
Find the slope intercept equation of the line passing through 21 with a slope of m equals 3?
The general equation of the line is y = 3x + c. Having only one coordinate (21) of a point on this line is not enough to evaluate c.

What is the slope intercept form of the line that has a slope of negative 3 and contains the points of 4 and negative 5?
The slope intercept form is: y=mx+b where m is the slope and b is the y-intercept. Since you already know the slope, you can plug that into the equation. y=-3x+b The only thing left to do is to find out what b is. To do this, plug the x and y value of the point it goes through into the equation and solve for b. Good luck.
How do you find the y intercept when they only give you the x intercept and the slope?
just kidding Y= mx+b so therefore you have a way to find y
How do you find the slope of an equation?
How to find slope if you are given the equation of a line in slope-intercept form:Slope intercept form is y = mx + b. m is the slope.For example, the slope of the line y = 3x + 7 is 3. (3 is m in the equation y = mx + b.) Another example, the slope of the line y = (-5/4)x - 4 is -5/4.If the line is in the form y = a number, then the slope is 0. For example, the slope of the line y = 3 is 0.If the line is int the form x = a number, then the slope is undefined. For example, the slope of the line x = 5 is undefined.How to find slope if you are given the equation of a line in point-slope form:Point slope form is y - y1 = m(x - x1). m is the slope.For example, the slope of the line y-6 = 2(x-7) is 2. Another example, the slope of the line y-5 = (3/2)(x+4) is 3/2.How to find the slope if you are given the equation of a line in standard form:Standard form is ax + by = c.One way to find the slope if a line in standard form is to convert it to slope-intercept form (y=mx+b).Here is an example using the line 3x + 8y = 283x + 8y = 28First move the x to the other side by subtracting 3x from each side:8y = 28 - 3xNext, divide each side by 8 (all three terms must be divided by 8):y = 28/8 - (3/8)xAfter simplifying the fractions, the formula is y = 7/2 - (3/8)xSlope-intercept form is y = mx + b, so the terms on the left side of the equation need to be rearranged for it to truly be in slope-intercept form:y = -(3/8)x + 7/2Be sure to keep the negative signs in front of their terms! (if you have any negative sings, there will be times when you won't.)The equation of the line 3x + 8y = 28 in slope-intercept form isy = -(3/8)x + 7/2. The slope of this line is -3/8 (see How to find slope if you are given the equation of a line in slope-intercept form, above).Another, faster way is to use the formula -a/b. The slope of the line 3x + 8y = 28 is -3/8. (Remember, this only works for standard form (ax + by = c).)
Has y intercept 8 and slope 0?
Yes, it is possible only when the x-intercept is infinite. so slope=y/x = 0.
Given the equation of a line y 25x - 2 the slope and y-intercept are respectively?

Find the slope of the line identified by the equation 4x plus 5y equals 20?
First rewrite the equation in the slope-intercept form. If trying to find only the slope, you can ignore the constant term. So, 4x + 5y = 20 5y = something - 4x y = something else - 4/5*x The slope is the coefficient of x in this form. That is, -4/5 or -0.8
