Question

What is the equation in slope-intercept form of the line through the points (2, -3) and (-3, 7)?

Answer 1

first find slope
m= 7+3/-3-2=10/-5=-2

Answer 2

slope intercept form
y=mx + b

Answer 3

I'm confused. What's the answer?

Answer 4

Well first you should determine the slope. Here's how to remember: "Slope is easy and it's fun. Just remember rise over run!"

From (-3, 7) to (2, -3), the line goes down 10 and over 5, so the slope is -10/5 = -2.

So your M is -2. Now just pick a point, substitute the x and y into your y=mx+b equation and solve for b. So picking (2, -3) gives:
y= m*x + b
-3 = -2*2+b
1 = b

So your equation is y = -2*x + 1
