Find the equation of the line parallel to the line y=3x+1 that contains the point (4,2)

y=3x-10

Step-by-step explanation:

We know that in order to be parallel to the equation y=3x+1, our new equation has to have the same slope of 3.

Because we know the slope will be 3 and we have the point (4,2) we can plug that in to find our new y-intercept.

y=3x+b

2=3(4)+b

2=12+b

b=-10

-10 will be the y-intercept and 3 is the slope.

answer: the equation matches the regression

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
