-19m-19 = 4m-4m+19
-19m-19 = 0+19
-19m = 19+19
-19m = 38
m = 38÷(-19)
m = -2
Answer:

y = -9 + 75 = 66
x = 27-(-11) = 27 + 11 = 38
slope = 66/28
Answer:
2nd option
Step-by-step explanation:
The zeros are the points on the x- axis where the graph crosses.
Since the graph crosses the x- axis at x = - 1 and x = 5, then
The zeros are x = - 1 and x = 5
9 / 5/8 =
9/1 / 5/8 =
9/1 * 8/5 = 72/5 = 14 2/5
