Question

5. which ordered pair is a solution of the equation y=-7x+2(1point)
(1,2)
(8,-54)
(5,-35)
(1,-7)

Answer 1

they are (x, y) points.

plug them in and only one of them should hold true.

for the first one: x = 1 & y = 2.

that means that if 2 = -7(1) + 2, then (1,2) is a solution to equation, i.e, it is on the line y = -7x + 2
