What you want to do is convert 20% into a decimal. Then you multiply that by 90. So, if 20% was a decimal(In this case it is 0.2) you do 0.2*90 which equals 18. So the answer is 18.

Answer:
y- intercept = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
+
= 1
Multiply through by 6 to clear the fractions
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide all terms by 3 )
y = -
x + 2 ← in slope- intercept form
with y- intercept c = 2
