7. Find the slope of the line that passes
through the points (-10,-3) and (5,9).

4/5

Step-by-step explanation:

you need to to use the the point slope formula which is m=y2-y1/x2-x1.

so you plug in 9--3/5--10 so as you know negative and negative equals positive so it would be 9+3/5+10 and it would equal 12/15. So you simplify it by  dividing it by 3 which will equal to 4/5.  

stethere all not eveanp-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).
