Slope-intercept form

Question

Find the equation in slope-intercept form (2,8) and (-2,0)

Answer 1

Let's write the slope-intercept form:

y=mx+b 

Let's find m the slope

m=(y₂-y₁)/(x₂-x₁₎

m=(0-8)/(-2-2)

m=-8/-4

m=2

let's find "b" through the (-2, 0) point

y=mx+b

0=2*(-2) + b

0=-4 + b

b=4

The equation in slope-intercept form (2, 8) and (-2, 0) is Y=2X + 4
