Answer:
y = -1/5x + 2.6
Step-by-step explanation:
Put the equation into slope intercept form:
5x - y = 12
-y = -5x + 12
y = 5x - 12
The slope of a perpendicular line will be the opposite reciprocal.
So, the slope of the new line will be -1/5
Then, plug this slope and the given point into the equation y = mx + b to find b
y = mx + b
3 = -1/5(-2) + b
3 = 0.4 + b
2.6 = b
So, the equation will be y = -1/5x + 2.6
Multiply the length by the width

Answer:
The original price of the paper is $3.50
Step-by-step explanation:
15% off coupon for the markers
Amount paid on the markers will be;
3- (15% of 3)
= 3-0.15(3) = 3-0.45 = $2.55
So the amount paid for the papers will be;
5.35 - 2.55 = $2.8
let the original price of the paper be x
x - 20% of x = 2.8
x - x/5 = 2.8
4x/5 = 2.8
4x = 2.8 * 5
4x = 14
x = 14/4
x = $3.50
