Answer:

The slope-intercept form of the equation of the line is (B) y=-3/10x+1/2

Explanation:

1. Find the slope of the line using the slope formula.

Points: (-5, 2) and (5, -1)

(-1-2)/(5+10)=-3/10

2. Find the y-intercept of the equation by plugging in the slope of the line and a coordinate of the line into the slope-intercept form.

Slope-intercept formula: y=mx+b

-1=-3/10(5)+b

b=1/2

3. Put the slope-intercept form of the equation of the line together.

y=-3/10x+1/2
