what is the equation for a line that passes through the points (3, -1) and (-6, 11)

Question

katrinakaif · Answer

To find an equation for these two given points, we must first find teh slope using:
y2-y1
-----
x2-x1 

In this case: (3,-1) : (x1,y1) and (-6,11) : (x2,y2)

Solve the slope first for me, and then I can guide you through the rest.

Good work. 
Now, we must use the formula: 
(y-y1) = m (x-x1) 

1) Pick any one of those two given points and substitute in for (x,y) 
2) Use the 'm' or slope we just solved for, and plug it in. 

See what you get and you have your equation.
