Question 534395: The directions say : Write the equation of the line that contains the points. Express final equation in standard form.
(-2,-3),(2,7)
I already have m=5/2. I dont know how to write the equation.

You can put this solution on YOUR website!
y = mx + b
.
m = (-3-7)/(-2-2)
m = -10/-4
m = 5/2
.
y = 5/2x + b
.
Use the point (2,7) to find 'b'.
.
7 = 5/2*2 + b
7 = 5 + b
b = 2
.
y = 5/2x + 2
.
y-intercept = (0,2)
.
x-intercept = (-4/5,0)
.
