Henry's current age is 10 times justin's current age. in 6 years henry's age will be 4 times justin's age. which system of equations can be used to calculate h, henry's current age, and j, justin's current age?
a. j = 10h
j +6=4(h+6)
b. j = h+6
j+4=h+10
c. h = 10j
h+6=4(j+6)
d. 10j
h+4=6(j+4)
explain too!

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
