Which of the following equations represent linear functions? y=x2−3x

4x+y=5

y=|2x+1|

y=−5

its y=-5x

Step-by-step explanation:

Why?

linear functions have only the slope, they dont include the y-intercept

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
