Answer:
y = x - 10
Step-by-step explanation:
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
Answer:
so the equation is y=-2x-4
Step-by-step explanation:
sub the points in the equation to find the y-intercept
y=x(-2)+b
0=-2(-2)+b
0=4+b
0-4=b
-4=b
If the total for the bill was the 284 written in then this is the answer as follows
284*0.25=71
Tip = $71.00
Answer:
$7.00
Step-by-step explanation:
The discount is 75% off. To answer this question, multiply n (the original price) by (1.00 - 0.75): 0.25n = $1.75.
Solving this for n, we get $7.00
Plug in 4 for X and you get 44
