Question

A line passes through the point (-5,-2) and (0,2) write the equation in point-slope form

Answer 1

y=0.8x+2

Explanation:

First, you would figure out the slope using the following equation: (y2-y1)/(x2-x1)=slope.

So, (2--2)/(0--5)= 4/5, or 0.8. This would be the slope.

Then, you would figure out b by putting a data point from the given ones. I chose (0, 2).

2=0.8(0) + b --> 2=0 + b --> 2=b

So, the final equation is y=0.8x+2

Answer 2

y=4/5x+2
