Sorry, I don't know. :/ Maybe you should use a graphing program like GeoGebra and try it? IDK. Sorry.

@shinalcantara can you help? plz

Answer 5

for you to get the ordinates of the points, all you have to do is to substitute the values available to the given equation
y = 7x
for point A, substitute the value of x which is -2 to find the value of y
do the same for point B

Answer 6

so I multiply -2 and 7?

Answer 7

which is -14
and 4 * 7=28
