Answer 1

Answer:which question do you need help on? :) I’d love to help

Answer 2

Explanation:

`15) f(x) = 10-(9)/(2)x\\10-(9)/(2)x = -53\\\\-(9)/(2)x=-53-10\\\\(-9)/(2)x= - 63\\\\x = -63*(2)/(-9)\\\\x = 7*2\\\\x = 14`

`17) (1)/(8)y = (-3)/(4)x - 1\\\\Multiply \ the \ entire \ equation \ by \ 8\\\\8*(1)/(8)y=8*(-3)/(4)x-1*8\\\\\\y = 2*(-3)x-8\\\\y = -6x - 8\\\\6x + y = -8\\`

`18) 5y = 35 + 10x\\\\(5y)/(5)=(35)/(5)+(10x)/(5)\\\\y = 7+2x\\\\-2x + y = 7\\\\`

`19)x -4y = 28\\\\ -4y = -x + 28\\\\(-4y)/(-4)=(-x)/(-4)+(28)/(-4)\\\\\\y = (1)/(4)x-7`

x = 0 ; y = 0 - 7 = -7 (0 .-7)

`x = 4 ; y = (1)/(4)*4-7 = 1 - 7 = -6 ; (4 , -6)\\\\\\x = -4 ; y = (1)/(4)*(-4) - 7 = -1 - 7 = -8 ; (-4,-8)`

Plot the points (0,-7) , (4,-6) and (-4 , -8) in the graph and join the points
