Question

Graph the equation

f(x)= 4(x)+5

Answer 1

Explanation:

The 5 is the y intercept. So that point will be (0,5). The 4 in front of the x is the slope. SO from (0,5) you would up up 4 and over 1. This will bring you to (1,9). You can do this in both directions.

Answer 2

Graph is a straight line.

Explanation:

We have given a function.

f(x) = 4x+5

We have to graph the function.

Sicce, f(x) = mx+c is equation of line where m is slope and c is y-intercept.

comparing given equation with equation of line, we have

m = 4 and c = 5.

putting f(x) = in given equation,we have

0 = 4x+5

x = -5/4 hence x-intercept = -5/4 = 1.25

Dram graph and point out the y-intercept and x-intercept.
