Question

show that the points a(1 2) b(-1 -16) and c(0 -7) lie on the graph of the linear equation y=9x-7 . please answer fast.

Answer 1

Answer:

so substituting any value of x or y should give you the corresponding coordinate value be it x or y when substituted into the linear equation

Step-by-step explanation:

for a(1 2)substitute any value and check if the equation gives you the corresponding coordinate you are looking for

so a(1 2) substitute say 1 into y=9x-7 if we get 2 then its linear

so y=9(1)-7

      =9-7

      =2

therefore since it corresponds to the y coordinate of the point 'a' then it is linear.

do the same for b(-1 -16) and (0 -7)

and substitute -1 into the equation to get -16 and substitute 0 to get -7

and hence if all the corresponding values are found and confirmed a b and c lie on the graph of the linear equation.
