Question

Which equation represents the graphed function?

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

Answer 1

y= 1/4x-2

Explanation:

Let's use the two points we have to find the equation.

y = mx + b

-2 = m(0) + b

So b = -2

-1 = 4m - 2

4m = 1

m = 1/4

Answer 2

y=1/4-2 is the correct answer. you go up one and over four. the y-intercept is -2
