Can someone explain what i’m supposed to do here?

The system of equations graphed below has how many solutions? y = 2x + 2

Find the equation of a line that is perpendicular to line g that contains (p, q). coordinate plane with line g that passes through the points negative 3 comma 6 and 0 comma 5 3x − y = 3p − q 3x + y = q − 3p x − y = p − q x + y = q − p

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
