Is the function y=3
x–10 linear or nonlinear?

It is linear

Step-by-step explanation:

When you put the coordinates on a graph it forms a line

x | 0   |    1

y | -10 | -20

You subtract -10 every point on the graph it forms coordinates on the graph and those coordinates are in a line

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
