Substitute x = 3 in any given equations. I will do in y = - x + 1

Therefore the answer is (3,-2)
Answer:
Step-by-step explanation:
y = -7/8x - 10
in y = mx + b form, which is what this is in, the slope can be found in the m position
y = mx + b
y = -7/8x - 10
so u have slope (m) = - 7/8 <====
the slope is not 10
the graph will not pass thru the origin
this equation does not represent a proportional relationship
Answer:
$7.5
