Answer:
Step-by-step explanation:
(-1,-2) , (3,10)
slope(m) = (10 - (-2) / (3 - (-1) = (10 + 2) / (3 + 1) = 12/4 = 3
y = mx + b
slope(m) = 3
u can use either of ur points....
(3,10)....x = 3 and y = 10
sub into the formula and find b, the y int
10 = 3(3) + b
10 = 9 + b
10 - 9 = b
1 = b
so ur equation is : y = 3x + 1
Answer:
step 3: he should have divided both sides by -7
