Answer: y=-3x+29
Step-by-step explanation:
First put in y-intercept form to find the slope

Slope of the 1st equation is 1/3- the slope of the line perpendicular is the opposite reciprocal, so in the case it is -3
Use the point and the new slope to write the new equation in point slope format

4x-(5-x)=8[4-(8+2x-1)]
answer: x= -19/21
1/2 & 3/10 .. in simplest form
(G) Is a function because it passes the vertical line test.
(H) Is not a function, does not pass the vertical line test.
(I) Not a function, does not pass the vertical line test.
