A•B=C
A•B=-21
Find factors of 21 ( it doesn't matter that it's negative ) that at up to be 4
It's 7and 3
Then put x^2+7x+3x-21 and then factor by grouping
Do the same steps for #2
Answer:
slope = -5/1
y-intercept = (0, -34)
Step-by-step explanation:
slope m = change in y ÷ change in x
= (-9 - -4) ÷ (-5 - -6)
= -5 ÷ 1
= -5/1
y = mx + b ⇒ y = -5x + b
substitute one of the points
-4 = (-5 x -6) + b
-4 = 30 + b
b = -34
Therefore, y-intercept = (0, -34)
