The formula for slope is:

slope=y2-y1/x2-x1 where (x1,y1) and (x2,y2) are points on the line

In this situation we know the x values of two points, and we know the slope, so we can solve for the missing y values.

slope=-7
(11,y1) (16,y2)

Now lets plug in the information into the formula.

slope=y2-y1/x2-x1
-7=y2-y1/16-11
-7=y2-y1/5
multiply both sides by 5
-35ft=y2-y1
distances cannot be negative so lets change -35ft to a positive number
35ft=y2-y1

The vertical distance between the two points is 35feet

Answer= A) 35ft

You babysit 15 hours each week for $6.00 per hour. You also earn $25.00 each

alexdok [17]

Answer:

$115

Step-by-step explanation:

Although it did say to complete the equation I put the answer just in case.

So, in order to calculate the total weekly income, I will use x which will equal the number of hours. The equation needed to calculate the weekly total income will be:

w = 6x + 25

Because we know the number of hours is 15, we can plug 15 in x:

w = 6(15) + 25

w=90+25

w=115

So, the total weekly income will be $115(don't forget to put the unit! In this case it will be the dollar sign).
