Answer:
the slope is -2/1
Step-by-step explanation:
(10,-9) and (3,5)
y2-y1/ x2-x1
5-(-9)/3-10
14/-7
This equals 0.146341463414634
72 3 plus 62 is 65 plus 7 is 72
Step 1 : Simplify both sides
-5(6a+21)=-15
(-5)(6a)+(-5)(21)=-15
-30a-105=-15
Step 2 : Add 105 to both sides
-30a-105+105=-15+105
-30a=90
Step 3 : Divide both sides by -30
-30a=90

-30 -30
a = -3
