Question

A line passes through the point (-2,7) and has a slope of -5

Answer 1

Answer:

y-7 = -5(x+2)

or

y = -5x-3

Step-by-step explanation:

We can use the point slope form of the equation

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

y-7 = -5(x--2)

y-7 = -5(x+2)

If we want the equation in slope intercept form

Distribute

y-7 = -5x-10

Add 7 to each side

y-7+7 = -5x-10+7

y = -5x-3

Answer 2

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

We know that the slope of the line (m)  will be -5

y = -5x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(-2, 7)

7 = -5(-2) + b

7 = 10 + b

-3 = b

y = -5x - 3
