The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m=2\to y=2x+b.

Put the coordinates of the point (-1, 5) to the equation of the line:

5=2(-1)+b

5=-2+b       <em>add 2 to both sides</em>

7=b\to b=7

Answer: y=2x+7

Charra [1.4K]

Answer:

$289.25

Step-by-step explanation:

First we should find out how much Ms. Maple would make in a week without overtime.

6.5 x 40 = 260

Now, let's figure out how much she makes per hour in overtime.

6.5 x 1.5 = 9.75

Now add up the hours of overtime.

9.75 x 3 = 29.25

Now we add the weekly wage to the overtime

260 + 29.25 = 289.25

For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.
