Use this system of equations to answer the questions that follow. 4x – 9y = 7 –2x + 3y = 4 What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation? What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

the answer is

a.

x = 42

y = 10

i got it down chief.

b: y = 2x + 2

step-by-step explanation:

y = 2x + 1

we want a line that is parallel, so it will have the same slope

the line is in the form y= mx+b, so the slope is 2

we have a slope and the y intercept (0,2)

since x is 0 we know the y point which is the y intercept

we can use y= mx+b to write the equation of the line

m is the slope and b is the y intercept

y = 2x +2
