How to find the slope of a hypotenuse triangle that not on a graph?

i think asking google will you get the answer to that question

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).

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

the answer is 1030 it's very simple math.
