Question 1: y-intercept
SOS TIP Equation of the straight line can be found using the equation y = mx + c where m = – x-intercept and c is y-intercept.
Question 3 (a):
Point (5, 6) can be determined whether that satisfy the linear equation or the linear inequalities by the substituting the point into the equation of the straight
line.
