Question

Find the missing value so that the two points have a slope of -13/2 (-2,y) and (0,-4)

Answer 1

Solution:

Note that:

• Given points = (-2,y) and (0,-4)
• Slope = -13/2
• Formula: y₂ - y₁/x₂ - x₁

Forming an equation:

• y₂ - y₁/x₂ - x₁ = Slope
• => -4 - y/0 - (-2) = -13/2

Solving the equation:

• => -4 - y/0 + 2 = -13/2
• => -4 - y/2 = -13/2
• => -4 - y = -13
• => -y = -13 + 4
• => -y = -9
• => y = 9

The missing value is 9.
