Point-Slope Form: (y - y₁) = m (x - x₁)
This format uses a single known point (x₁,y₁) and the slope m (which is also a known value)
From the problem statement:
m (the slope) = 3/2
single known point (x₁,y₁) = (11,-5)
x₁ = 11
y₁ = -5
(y - y₁) = m (x - x₁)
(y - (-5)) = (3/2)*(x - 11)
Slope Intercept Form
y = mx + b
(y + 5) = (3/2)*(x - 11)
2*(y + 5) = 2*(3/2)*(x - 11)
2y + 10 = 3x - 33
2y + 10 - 10 = 3x - 33 - 10
2y + 0 = 3x - 43
2y = 3x - 43
2y / 2 = (3x - 43) / 2
y = (3/2)x - 43/2
Slope Form of Equation for Line “b”: y = (3/2)x - 43/2
