Question

A line crosses the coordinates (-3,5) and (4, -2). What is the slope-

intercept form of the equation of this line?

Answer 1

y=-x+8

Explanation:

y = mx + b is the basic formula

use the formula y2-y1/x2-x1 to get the slope to get m

-2-5/4-(-3)

-7/7

-1

then use the point slope formula y-y₁=m(x-x₁)

y-5=-1(x-(-3)

y-5=-1x+3

y=-x+8
