4. here is an equation that is true for all values of x: 5(x + 2) = 5x + 10. elena saw this equation and says
she can tell 20(x + 2) + 31 = 4(5x + 10) +31 is also true for any value of x. how can she tell? explain
your reasoning

i would need to see the dot plot : )

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
