Find an equation of the line through (3,6) and parallel to y = 4x - 7.

FromTheMoon [43]

Answer:

$y=4x-6$

Step-by-step explanation:

Okay, to do this we must understand what parallel means.

parallel means that that one line will NEVER touch the other. In order for this to happen they must be increasing (or decreasing) by the SAME rate. I.e the slope of your line must be the same as the lin in question thus our equation looks like,

$y=4x+c$ .

Now lets find $c$ .

To do this, plug the point (3,6) into the equation

6=4(3)+C

6=12+C

-6=C

Thus now that we know C, our equaiton is

$y=4x-6$

Lorna and Robin work as consultants and get paid per project. Lorna is paid a project fee of $35 plus $20 per hour. Robin is pai

vazorg [7]

Answer: Y=54x + 60

Step-by-step explanation:

You add both project fees together ( 35 + 25 = 60) then you add together the hourly rates (20 + 34 = 54) and the hourly rate is your slope because it’s per hour and the 60 is your y intercept because it’s paid upfront.
