What is the equation of the line that passes through the point (-4, 2) and<br> has a slope of -2?
sammy [17]

Answer:

y-2 = -2(x+4)

or

y = -2x-6

Step-by-step explanation:

We can use the point slope form of a line

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

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

y-2 = -2(x+4)

If we want the equation in slope intercept form

Distribute

y-2 = -2x-8

Add 2 to each side

y-2+2 = -2x-8+2

y = -2x-6

Mademuasel [1]
Here is the equation:
(30 \div 50) \times 60
30 divided by 50 equals 0.6.
We do this because 30 divided by 50 meams you get the miles per minute.

But there are 60 minutes in an hour, so we multiply 0.6 times 60. This comes out to
