<h2>Greetings!</h2><h3>To find that these two slopes are the same, you can calculate the gradients of the two lines, which is what all the options are.</h3>
The equation for the gradient is:
<h3>Where the differeny y and x values are the two co-ordinates of the lines starting and end point.</h3>
Take the line JL, one of the two sets of coordinates are (-4 , 0) and the other set is (-7, 4)
<h3>If you use these two sets to substitute into the equation for the gradient, you can use either y coordinates in both sets as y1 or y2 as long as this method is throughout and the x value is the same in both sets ( both numbers are x1 and y1, one cannot be x1 and the other y2).</h3>
Lets use ( -4 , 0) and (-7 , 4) which are the coordinates for JL.
y1 = 4 and y2 = 0
0 - 4
<h3>Now lets use the two x values:</h3>
x1 = -7 and x2 = -4
(-4) - (-7)
<h3>Simply put these two equations in a fraction:</h3>
<h3>Now choose another two sets of values for MP, such as (-10 , 8) and (-1 , -4)</h3>
y1 = 8 and y2 = -4
-4 - 8
<h3>Lets use the two x values:</h3>
x1 = -10 and x2 = -1
-1 - (-10)
<h3>Put them into a fraction:</h3>
<h3>Now these two fractions can be put together, putting an equal sign in middle because they both are same gradient:</h3>
<h3>Meaning that your answer if G!</h3>
