Question

A new math problem i need help with

Answer 1

y = 0.25*x + 2

Explanation:

m = (y1 - y2) / (x1 - x2) = (4 - 0) / (8 - (-8)) = 4/16 = 1/4 = 0.25

y = m*(x - Px) + Py = 0.25*(x - (-8)) + 0 = 0.25*x + 2

Answer 2

y = 1/4x +2

Explanation:

We have two points (-8,0) (8,4)

We can find the slope

m = (y2-y1)/(x2-x1)

= (4-0)/(8--8)

= 4/(8+8)

= 4/(16)

= 1/4

We can use point slope form of the equation

y-y1 = m(x-x1)

y-4 = 1/4 (x-8)

Distribute

y-4 = 1/4x -2

Add 4 to each side

y-4+4 = -1/4 x -2+4

y = 1/4x +2
