1). the answer is (B). -1,-4 because if you plug those numbers into the equation you get -4=4(-1) which is true.
2). none of the answers work because if you plug the numbers in, the equation will not work.
#1
= 9
Let's solve your equation step-by-step.
8.88=4.44(x−7)
Step 1: Simplify both sides of the equation.
8.88=4.44(x−7)
8.88=(4.44)(x)+(4.44)(−7)(Distribute)
8.88=4.44x+−31.08
8.88=4.44x−31.08
Step 2: Flip the equation.
4.44x−31.08=8.88
Step 3: Add 31.08 to both sides.
4.44x−31.08+31.08=8.88+31.08
4.44x=39.96
Step 4: Divide both sides by 4.44.
#2
= y = -3
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by 5.

9.616 or 3.06pie. Let me know how that works out
Answer:
y = -3/4x-1/4
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b
where m is the slope and b is the y intercept
y = -3/4x +b
We have a point (-5,4)
4 = -3/4 (-5) +b
Changing to a common denominator
16/4 = 15/4 +b
subtracting 15/4 from each side
16/4-15/4 = -15/4 +15/4 +b
1/4 = b
y = -3/4x-1/4
