Write the equation of the line that has a slope of 2 and passes through the point (-3,4).
dalvyx [7]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Data

slope = m = 2

Point (-3, 4)

Process

1.- Substitute the data in the line equation

                     y - y1 = m(x - x1)

                     y - 4 = 2 (x + 3)

2.- Expand

                     y - 4 = 2x + 6

3.- Solve for y and simplify

                     y = 2x + 6 + 4

                     y = 2x + 10

Which best describes the structure of the expression (5 ⋅ 46.4) − (3.2 ⋅ 13.7)
aksik [14]
You are subtracting the results in the parenthesis.

I would go with a difference. 

Since 8 is being multiplied by 23.6 and -7.8, I would say product.

"A" is the best answer choice.

I hope this helps!
