Step-by-step explanation:
substitute 8 for x and 5 for y
56-50=3??! , which is not true 56-50= 6 not 3 as the model says , therefore the model is not good.
checking by (-12,-9)
-84 +90 = 3?
The constant value in the equation should be 6 and not 3 (the y intercept should be -3/5)
7x-10y=6
10y= -7x+6
y= 7x/10 -6/10
y= 7x/10 -3/5
