Answer:

Slope = 3

y intercept = -8

y = 3x - 8

Explanation:

From the table shown, we can make use of the coordinate points

(0, -8) and (1, -5)

Slope m = y2-y1/x2-x1

m = -5-(-8)/1-0

m = -5+8/1-0

m = 3/1

m = 3

Slope = 3

The standard form of an equation is y = mx+b

b is the y intercept

Substitute m = 3 and (0, -8) into y = mx+b

-8 = 3(0) + b

-8 = b

b = -8

Hence y intercept is -8

Get the required equation

Recall that y = mx+b

y = 3x + (-8)

y = 3x - 8

This gives the required equation
