[1 Mark Question Answer]

Question 11 Mark

Find the slope and y-intercept of the line: y = 4

Answer

y = 4
Comparing this equation with y = mx + c, we have:
Slope = m = 0
y-intercept = c = 4

Question 21 Mark

Answer

Slope of $A B=\frac{5+3}{-2-0}$
Slope of $A B=\frac{8}{2}$
Slope of $A B=-4$
Slope of the line parallel to AB = Slope of AB = -4
