Question

PLEASE HELP!

Answer 1

Answer:

y=2x+6

Step-by-step explanation:

We use this following formula to find the equation:

$y-y_{1} =m(x-x_{1} )$

Now, we substitute the values in $y_{1}$ and $x_{1}$ :

$y-8=2(x-1)$

Distribute the 2 inside the parentheses:

$y-8=2x-2$

Now add 8 to both sides:

$y=2x+6$ is your answer.

Answer 2

Step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

y=2x-1

2=slope

-1=y intercept

NOTE: parallel lines have the same slope

and we put the point (1,8) into y=mx+b with (x,y)

8=1m+b

now we put in 2 for the slope

8=1(2)+b

6=b

2=m

now insert that back into y=mx+b

y=2x+6

and that is the line that is parallel to y=2x-1 and passes through (1,8)

Hope that helps :)
