That’s weird, it should be (-2,-7). Try (-2,7)
Find gradient by changing form of equation: y = 2/3x + 4. Gradient is 2/3.
Find y intercept of other line by substituting the coordinates: -8/3
Use information to write out equation of line: y= 2/3x - 8/3
Convert to standard form: -2x + 3y = 8.
Hope this helps :)
