Answer:
3/8
Step-by-step explanation:
Rearrange, find common denominator.

Answer:
Z = 34
Step-by-step explanation:
From the series, we have that:
a = -2
a + d = 7
Hence, -2 + d = 7
∴ d = 7 + 2 = 9
a + 2d = X; a + 3d = Y and a + 4d = Z
-2 + 4(9) = Z
∴ Z = 36 - 2 = 34
Formula for slope: y2-y1/x2-x1
Plug in values.
3-8/-4-(-7)= -5/3 = slope
42-1/36-12=41/24=slope
