Answer:
y = -2/3x + 23/3
Step-by-step explanation:
Let equation of the line be y = mx + c
m = (3-5)/(7-4) = -2/3 gradient/slope formula
sub (4, 5)
5 = -2/3 (4) + c
c = 23/3
therefore, equation of the line is y = -2/3x + 23/3
Hope it helps! :)
This is a topic called coordinate geometry. If you would like to find out more you can follow learntionary on instagram. I'll be posting some notes on coordinate geometry soon and I'll also post other useful math stuff as well :)

Answer:
A) 4x − 5y = 2
10x − 7y = 18
Step-by-step explanation:
4x − 5y = 2 --> (1)
3x − y = 8 --> (2)
(1) + 2(2)
4x - 5y = 2
6x - 2y = 16
10x - 7y = 18
