Josie graphed a like with the same slope as y=3x, but that intercepted the y-axis 6 units above y =3x. what is the equation of the line josie graphed?

a) y = 3x + 6

b) y = 6x

c) y = 9x

d) y = 9x + 6

A) y=3x+6

Step-by-step explanation:

A line's equation is written as y=mx+b where m is the slope and b is the y-intercept. If the line has the same slope as y=3x then m=3. It also crosses 6 units above y=3x. y=3x crosses at (0,0) since b=0 so b=6 in the other line. This means the equation is y=3x+6.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
