<u>Answer</u>:
c = 9
<u>Explanation</u>:
given: f(x)=3x-7
<em>if f(c) =20</em>
To solve this replace x with c and then y is 20.
<u>Solve</u>:
3c - 7 = 20
3c = 27
c = 27 ÷ 3
c = 9
Y=1/3x while m=0................

You only need two separate ordered pairs for the slope formula
For this case we have the following equation of a line:

To find the point of intersection with the x axis, we make y = 0:

We clear the value of "x":

So, the x-intercept of the line is 5.
To find the point of intersection with the y axis, we make x = 0:

We clear the value of "and":

So, the y-intercept of the line is 20.
