What is the equation of the line that passes through the point (2,-4) and has a slope of -2

Mathematics
1 answer:
kvv77 [185]2 years ago
3 0

Answer:

The answer is

\huge y =  - 2x

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have

y + 4 =  - 2(x - 2) \\ y + 4 =  - 2x + 4 \\ y =  - 2x + 4 - 4

We have the final answer as

<h3>y = -2x</h3>

Hope this helps you

Candy is on sale for $0.75 each. you have a coupon for $0.25 off your total purchase. Write a function rule for the cost of n pi
alekssr [168]
<span>The answer is B. C(n) = 0.75n - 0.25.
Let n be the number of pieces. The price for 1 piece is $0.75. The price C for n pieces without a coupon is n * $0.75: C(n) = 0.75n. The coupon value is $0.25. So, this value must be subtracted from the total price of n pieces. Since the coupon values in independent on the number of pieces, the price C for n pieces with the coupon will be: C(n) = 0.75n - 0.25. Therefore, the correct choice is B.</span>
