The table below gives the equations of three lines.
Line 1: 4x -2y -12 = 0
Line 2: y=5
Line 3: 3y = 9x - 8
Which line has the greatest slope?
I'm okay with converting the lines 2 & 3 into equations of the line, it's just finding out the slope, i.e. there's no x1 and y1?
If you put an equation in the form y=mx+c then the coefficient of the x value is the slope.
Therefore if you rearrange line 1 it becomes y=2x-6 so it has a slope of 2.
Line 2 has no x value so it has a slope of 0
and line 3 has a slope of 3
Therefore line 3 has the greatest slope.
