Answer: y = -2x + 9

Explanation:

Points through which the line passes through are: (-2,13) and (4,1)

The slop intercept form will be in terms of:

y = mx + c

Find m first which is the slope:

= (Y₂ - Y₁) / (X₂ - X₁)

= (1 - 13) / (4 - (-2))

= -12 / 6

= -2

Using a point on the line and the slope, calculate c which is the y intercept:

Using point (-2,13) :

y = mx + c

13 = -2 * -2 + c

13 = 4 + c

c = 13 - 4

c = 9

Slope intercept form of line is therefore:

y = -2x + 9
