just kidding Y= mx+b so therefore you have a way to find y

Q: How do you find the y intercept when they only give you the x intercept and the slope?

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.

4x - 2 = 3x is equivalent to x = 2.This is an equation in x only and cannot be expressed in the slope intercept form because the slope is undefined and the y-intercept does not exist.

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

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.

That's all you need to know in order to draw the graph. Note that it doesn't matter what form the equation is written in. The form of presentation doesn't change the slope or intercept.

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

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.

Yes, it is possible only when the x-intercept is infinite. so slope=y/x = 0.

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?

That's all you need to know in order to draw the graph. Note that it doesn't matter what form the equation is written in. The form of presentation doesn't change the slope or intercept.

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

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.
