Question

Draw the graph of the equation 3x-4y=12 from the graph find the value of y when x= 8​

Answer 1

y = 3

Explanation:

3x - 4y = 12

3(8) - 4y = 12

24 - 4y = 12

- 4y + 24 = 12

- 4y + 24 - 24 = 12 - 24

- 4y = - 12

- 4y ÷ - 4 = - 12 ÷ - 4

y = 3

Slope:
`(3)/(4)`

y - intercept: (0, - 3)
