Answer:
<em>(D.)</em> $218.00
Step-by-step explanation:
$218.00 <em><- original (retail) price</em>
<u>- $ 15.00</u>
$203.00 <em><- discounted price </em>
y = x - 10
Find the slope:
-4 - (-8) ÷ 6 - 2
-4 + 8 ÷ 6 - 2
4 ÷ 4
= 1
Substitute into the slope-intercept equation:
y = mx + b
Let's use the first coordinate (2,-8) for the x and y values
m = 1
-8 = 1(2) + b
-8 = 2 + b
-2 -2
-10 = b
Write equation:
y = 1x -10 or y = x -10
