Answer:

y=mx+b

m=sloe

b=yint

given

slope=-2

yintercept=8

Step-by-step explanation:

y=-2x+8

add 2x to both sides

2x+y=8

minus 8 both sides

2x+y-8=0

It is 3 but it is different a little bit because you need to move the y to the other side

Answer:

y = 1/5x - 6/5

Step-by-step explanation:

Step 1: Write out known variables

m = 1/5

y = 1/5x + b

Step 2: Find <em>b</em>

-1 = 1/5(1) + b

-1 = 1/5 + b

b = -6/5

Step 3: Write linear equation

y = 1/5x - 6/5

Answer:

+$90;

$1,600

Step-by-step explanation:

The equation, y = 1600 + 90x, given to us tells us much about the situation described above.

y = total pay

x = number of copies of Math is fun

1600 = y-intercept, that is the starting value or the pay he gets only if Sam sold 0 copy of Math is fun. That is, when x = 0, y = 1,600.

90 = unit rate or the change in the total pay for each copy of Math is fun that Sam sells.

Therefore, our answers would be:

+$90, and $1,600
