4y - 5 = 7x
∴y = 7/4x + 5/4
slope = 7/4, or 1.75
4y - 5 = 7x
∴4y/7 - 5/7 = x
∴4y/7 - 5/7 = 0
∴4y = 5
∴y = 1.2
the y-intercept is 1.2

7x + y = 4y = 4 - 7x
-1.5
x=3 y=9 7x + 4y =? (7 * 3) + (4 * 9) = 57 Remember always multiply/divide before you add/subtract
It works out that the solutions are: x = 3 and y = 2
