Q:
A line passes through the point (10, -4) and has a slope of -1/2. Write an equation in slope-intercept form for this line.
Accepted Solution
A:
General formula to make slope-intercept form
y - yβ = m(x - xβ)
From the question, we know that
m = -1/2
(xβ,yβ) = (10,-4)
Put the number to the formula
y - yβ = m(x - xβ)
y - (-4) = -1/2(x - 10)
y + 4 = -1/2 (x - 10)
y + 4 = (-1/2)x + 5
y = (-1/2)x + 1
