By rearranging the equation in the form of y=mx+c,
where:
m=Gradient
c=y-intercept
1. x%2By=4
y=-x%2B4
y=highlight%28-1%29x%2B4
Thus, the value of m = -1 which means the gradient, m of the line is -1.
2. 3y=2x-4
%283y%29%2F3=%282x%2F3%29-4%2F3
y=highlight%28%282%2F3%29%29x-4%2F3
Same goes to this equation. The value of m=2%2F3 which means the gradient, m of the line is 2%2F3.
3. 5x-4y=12
-4y=-5x%2B12
%28-4y%29%2F-4=%28-5x%29%2F-4%2B12%2F-4
y=highlight%28%285%2F4%29%29x-3
The value of m=5%2F4 which means the gradient, m of the line is 5%2F4.
