-3x+9y =18
add 3x to each side
9y = 3x+18
divide by 9
y = 3/9 x +18/9
y = 1/3 x+2
the slope is 1/3
the y intercept is 2
-3x+9y =18
let y=0 to find the x intercept
-3x=18
divide by -3
x=-6
the x intercept is -6
Answer:
92º
Step-by-step explanation:
(2x-2)º=x+45º
2x-2=x+45
2x-x=45+2
x=47
____________
22x-2=2(47)-2=92º
