Answer:

slope = 1

y-intercept = 6

Equation: y = x+6

Step-by-step explanation

The coordinates of A and F are (2, 8) and (-2, 4) respectively

A =(2, 8), F = (-2, 4)

Get the slope

Slope m = y2-y1/x2-x1

Slope m = 4-8/-2-2

Slope m = -4/-4

Slope m = 1

Get the y intercept;

Substituting the coordinate A(2, 8) and m = 1 into y = mx+b to get b;

8 = 1(2) + b

8 = 2 + b

b = 8 - 2

b = 6

Hence y - intercepr b is 6

Get the equation;

Recall that y = mx + b where;

m = 1

b = 6

Substitute;

y = 1x + 6

y = x+6

Hence the required equation is y = x + 6
