The answer is B = (-1, -5)
Because -1 to 4 is 5 which is the run from
rise/run
So we would apply 2 - 7
Which would be - 5

Answer:
C. $7.70
Step-by-step explanation:
First, you have to calculate the 10% of the price and subtract that from the price to find the amount of the discount:
$27*10%=$2.7
Now, you can add the amount of the discount plus the coupon to find the amount that the customer saved:
$5+$2.7=$7.7
According to this, the answer is that the customer saved: C. $7.70
First find the slope:
m = ( 2 - 1 ) / ( 0 - (-1) ) = 1 / 1 = 1
Set up slope-intercept form:
y = 1·x +2
Now move x and y to the left and leave 2 on the right:
-x + y = 2
This is also equivalent to x - y = -2, so that just depends if you want your x coefficient to be positive or negative.
