Hi there!

To derive an equation given the points, we can use the slope formula:

Plug in the corresponding coordinates:

Simplify:

Therefore, we have:
y = -4x + b
Plug in the x and y values for a coordinate to solve for b:
2 = -4(1) + b
2 = -4 + b
b = 6
The equation is:
y = -4x + 6. The correct answer is D.
Answer:
20% of $886.20 is 177.24 so the better deal would be 20% off
Step-by-step explanation:
Answer:
5 x 3 1/2 x 1 1/2
5 x 7/2 x 3/2 = 26 1/4, in decimal form: 26.25
Multiply across, but first make it all improper fractions.
Answer:
the answer would be 9 I think
