Answer:
m ≤ 27 or m > 11
m is all real number since we have the or
Step-by-step explanation:
m − 11 ≤ 16 or 15 − 2m < −7
Lets solve the one on the left first
m − 11 ≤ 16
Add 11 to each side
m-11+11 ≤ 16 +11
m ≤ 27
Now lets solve the one on the right
15 − 2m < −7
Subtract 15 from each side
15 −15- 2m < −7 -15
-2m < -22
Divide by -2, remembering to flip the inequality
-2m/-2 > -22/-2
m > 11
a = -3
35 = -7a + 14
-14 + 35 = -7a + 14 - 14
21 = -7a
21/-7 = -7a/-7
-3 = a

Rise over run, for every time the y-value increases by one, the x-value also increases by one; 1/1=1. The slope formula is y2-y1/x2-x1.
