Answer:

b. y = −0.5x + 5.5

Step-by-step explanation:

Well first we need to find the slope of line CD.

To do that we'll use the following formula,

\frac{y^2-y^1}{x^2-x^1}

We'll use the points (1,1) and (3,5)

So y2 is 5 y1 is 1 so 5-1 = 4

3-1 = 2

<u>Slope = 2x</u>

If the slope of line CD is 2x we can cross out choices C and D.

Two lines that are perpendicular to each other have reciprocal slopes,

meaning is the slope of line CD is 2 then its perpendicular lines slope should be -.5.

If the perpendicular line goes through point (-1,6), the y intercept would be, 5.5.

Look at the image below ↓

<em>Thus,</em>

<em>the answer is option b. y = −0.5x + 5.5.</em>

<em>Hope this helps :)</em>

All you do is 1x+2x+5x=8x then you turn 4 s into pints. 1 gallon equals 4 pints 4*4=16 pints. 8x=16 x=2. Then you multiply everything by 2

1*2=2 
2*2=4
2*5=10
