Step-by-step explanation:
hello !
to solve this system of equations, first, we substitute the equation to the <em>y </em>variable in the equation
. Therefore, we get:
now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:
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
