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 = 28
3x + 8y = 28
First move the x to the other side by subtracting 3x from each side:
8y = 28 - 3x
Next, divide each side by 8 (all three terms must be divided by 8):
y = 28/8 - (3/8)x
After simplifying the fractions, the formula is y = 7/2 - (3/8)x
Slope-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 + 7/2
Be 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 is
y = -(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).)

How do you find the equation of a line by the slope?
An equation of a line requires two parameters. The slope, by itself, is not enough.
How do you find a slope to a equation?
the slope formula is y=mx+b slope-intercept form of an equation of a line. where m=slope and b=the y-intercept
How do you find slope of an equation?
Slope or gradient = (y2-y1)/(x2-x1)
How do you find the slope of a line with the equation y equals 3?
the slope is 0
How do you find the slope and y intercept of an equation?
The slope is the gradient which is y2-y1/x2-x1 To find the y int you set the equation of the line equal to zero i think :/
