Question

Hat function is represented by a line with slope −2 that passes through the point (0, 4)?

Answer 1

Answer:

C

Step-by-step explanation:

You can use the formula y=mx+b

f(x) is the same as y

m=slope

b=y intercept

We know that the slope is -2 so which answer has -2 as b? (Which one has a -2 before the x?)

Y Intercept is where the line crosses though the y axis. The point of the y intercept will ALWAYS have 0 as x. So (0,4) is the y intercept. You could also say 4 is the y intercept. Which one has 4 as b? (Which one says +4 after -2x)

The only answer that matches is C.

I hope thay made sense.
