Slope line and y intercept need help!

Gerrard found the slope and y-intercept of a line using equation for the line.Is his answer correct?If not,explain what he did wrong and provide the correct answer.

write the slope and y-intercept of the equation:-3y=3/4x+(-2)

answer:slope:3/4                  y-intercept:-2

 

find the and and y-intercept

 

4y=3x+5   

y=5/2x+(-4)

-2x=-2y--2/3

y=5--1/7x

 

 

write the missing numbers

m=y--y^1

      --------

      x--x^1

 

 

next part1

m=y--?

     x--?

 

m=?
