Answer:

y = -4x + 2

Step-by-step explanation:

y = mx + b ( slope-intercept)

1. Find Slope:

[tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]

Lets name 2 as y2 and 10 as y1. And 0 as x2 and 2 as x1.

[tex]\frac{2-10}{0-2}[/tex]  =  [tex]\frac{-8}{2}[/tex] = -4

m/slope = -4

2. Find y-intercept:

[tex]y = mx +b[/tex]

2 = -4(0) + b

= 2 = b

Y-intercept/b = 2

3. Put into slope-intercept form:

y = mx + b

= y = -4x + 2

Hope that helps! :D
