The given equation is -9x + 8 = y
There are two variables x and y
The highest degree of the each variable is 1, so it is the linear equation with two variable.
Consider some value for x and then solve it for y;
Let x = 1
-9x + 8 = y
-9(1) +8 = y
-9 + 8 = y
y = -1
(1,-1)
Let x = 0
-9x + 8 = y
-9(0) + 8 = y
y = 8
(0,8)
Let x = (-1)
-9x + 8 = y
-9(-1) + 8 = y
9 + 8 = y
y = 17
(-1, 17)
