Question

15) Write an equation that is parallel to y = -2x + 1 and passes through the point (1,5)

Answer 1

Can you identify the slope of y=-2x+1

Answer 2

For parallel lines, the slopes are the same. For the first equation, the slope is -2, so for the second one, it needs to be the same. You need to use point slope form/equation to figure out the equation.
Point Slope: y – y1 = m(x – x1) (m is slope)
Plug in the points given:
y-5=2(x-1)
y-5= 2x-2
y=2x+3 <-- final answer

Did this help?

Answer 3

agree ^^^

Answer 4

yes thank you

Answer 5

That's not what I got...

Answer 6

How did you do it?

Answer 7

The same as you, just check your 'm'

You put 2 instead of -2

Answer 8

My bad.
It would then be y= -2x+7, right?

Answer 9

Yep.

Answer 10

Okay, thanks
