To find the y-intercept, we can convert this to slope-intercept form, or replace the value of x with 0 and solve for y.
We'll do both first.
-x + 5y = 45
5y = 45
Divide both sides by 5.
y = 9
Now let's convert it to slope-intercept.
-x + 5y = 45
Add x to both sides.
5y = 45 + x
Divide both sides by 5.
y = 1/5x + 9
y = 9
<h3><u>The y-intercept of our line is 9.</u></h3>
Answer: C because that is the actual definition.
X=(-9y/8)-29/8
y=(-8x/9)-29/9
Answer:
7 x 9 = 63, 63 divided by 2 = 31.5,
31.5 x 4 = 126
9 x 9 = 81
Add given areas:
126 + 81 = 207 in2 is your answer
