Question

Write a rule for the inward function whose graph has a slope m=2, and a y-intercept b=-4

Answer 1

y= 2x - 4

Explanation:

Answer 2

Explanation:

The slope is given as m = 2

The general equation is y = mx + b

So far what we have is y = 2x + b

The y intercept is the value of y when x = 0

-4 = 2(0) + b

b = - 4

Therefore the equation is y = 2x - 4
