Answer:

y+4 = 2(x+3)

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/ (x2-x1)

   = (2--4)/(0--3)

    = (2+4)/(0+3)

    = 6/3

   = 2

We want to use the point slope form of the equation for a line

y-y1 = m(x-x1)

We know the slope =2 and the point (0,2)

y-2 = 2(x-0)

y-2 = 2x

We could also use the other point (-3,-4)

y--4 = 2(x--3)

y+4 = 2(x+3)

7c??? help on 7c???? please?!

It would be a 12.5% increase. First you find her monthly wages: $10.50 x 160 hours= $1680 a month. Her insurance is $210/month. So you need to find what percentage 210 is of 1680. So 1680*x=210 . Solve for x by dividing 1680 on both sides and you get 0.125. Multiply by 100 to get the percentage and you get 12.5%. Check your answer by multiplying 1680 x 0.125 and you get 210.
