-1 - 8 / 2 + 1 = -9 / 3 = -3
-1 = -3(2) + b
-1 = -6 + b
Add 6 to both sides.
5 = b
y = -3x + 5
First you had to rewrite the problem with eighteen as the three times six is equal to eighteen.

Then you factor it out by the common term of six.

Final answer: 
Hope this helps!

Answer: x is 6
Step-by-step explanation:
where a and b are x intercepts given to us.
So rewriting in factored form:
y = (
)(
)
so now you have to simplify it using the formula


y=
-
+
so with this formula
we can find the x coordinate

and the answer would be 6
24.75 would be your answer you just subtrct i think
