Question

Solve for y, give the slope and y intercept 5y=20, -y + 3=15x, y +1/3x=17

Answer 1

`5y=20` Equation


`y=4` Divide by 5 on both sides


`5(4)=20` Plug in for y


`20=20` Simplify

y=4
slope= 0
y-intercept= 4


`^(-)y+3=15x` Equation


`^(-)y=15x-3` Subtract 3 from both sides


`y=-15x+3` Divide both sides by -1


`- (^(-)15x+3) +3=15x` Plug in for y


`15x-3+3=15x` Distribute -1 into the parenthesis


`15x=15x` Further simplified

y= -15x+3
slope= -15
y-intercept= 3


`y+ (1)/(3)x=17` Equation


`y=^(-)(1)/(3)x+17` Subtract 1/3x from both sides


`(^(-)(1)/(3)x+17 )+(1)/(3)x =17` plug in for y


`17=17` Simplify

y= -1/3x+17
slope= -1/3
intercept= 17
