1st eq.  4x +5y = 7

2nd eq.  y = 3x+9

 replace the value of y from 2nd eq for y in 1st eq.

4x +5(3x+9) = 7

now distribute:

4x + 15x + 45 = 7

 combine like terms:

19x + 45 = 7

subtract 45 from each side:

19x = -38

divide both sides by 19

x = -38/19 = -2


now use value of x in 2nd eq to solve for y

y = 3(-2) +9 = -6 + 9 = 3

x = -2, y = 3

Contact [7]

Answer:

y= -(1/5)x +1

Step-by-step explanation:

Find slope:

(2+1)/(-5-10) = -1/5

Plug a point and slope into equation (I used -5,2):

y-2=-1/5(x+5)

Change it to slope-intercept form:

y-2=-1/5(x+5)

y-2=-1/5x-1

y=-1/5x+1

8.3% since 8.3 times 12 equals 100 you would multiply by 1 and that would make it the percent.
