Answer:
27/35.
I can break it down for you to understand if u want.
Step-by-step explanation:
Ok, so to so to find gradient with two coordinates you can use this formulae.. m=y2-y1 over x2-x1. Example A=(4,3) and Q(8,5) 4 would be x1, 3 would be y1 , 8 would be x2 and 5 would be y2 put them in the formulae and work it out. its pretty easy after you put them in :)
I believe you are right, it is C
If you go through each option, it would be correct.
-5(7) = -35 + 3 = -32
-3(7) = -21 + 3 = -18
-1(7) = -7 + 3 = -4
6(7) = 42 + 3 = 45
7(7) = 49 + 3 = 52
So the equation y= 7x+3, as you selected would be correct.
Please correct me if I am wrong and have a good day!
