Answer:
I think it is -4 and -3
Step-by-step explanation:
Amount of money received when x tickets are sold=$Y
Number of tickets sold=X
Slope of line=
And , y- intercept = 8
Equation of line having slope m and y-intercept c is given by,
y = m x + c,
Expressing the above statement in terms of linear equation in two variable i.e a line is
Y = X + 8
Plug in (7, 12) for x and y in the equation.
12 = 2(7) + 1
12 = 14 + 1
12 ≠ 15
Therefore, (7, 12) is not on the straight line equation.
