Someone pls help me. I'm confused.

g(x)={490x}+100

the image of (6, 9) under a dilation is (4, 6). the scale factor is

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
