To have the slope, the lines must have the same gradient. Gradient of the given line = (-7--1)/(-1--4) which is the same as (-7+1)/(-1+4.) This gives -6/3= -2
Thus the correct answer will have a gradient of -2 Option 1: There is no X component therefore no gradient, therefore this is wrong Option 2: Gradient = (2-4)/(1-1)= impossible, therefore this is wrong Option 3: This has a gradient of -1/2 therefore this is also wrong Option 4: Rearange the formula to find Y 3Y= 5-6x Y= 5/3 -2x Therefore option 4 has a gradient of -2x therefore will have the same slope as the given one
