Question

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.

Answer 1

General formula to make slope-intercept form
y - y₁ = m(x - x₁)

From the question, we know that
m = -1/2
(x₁,y₁) = (10,-4)

Put the number to the formula
y - y₁ = m(x - x₁)
y - (-4) = -1/2(x - 10)
y + 4 = -1/2 (x - 10)
y + 4 = (-1/2)x + 5
y = (-1/2)x + 1

Answer 2

In this exercise we have to use slope knowledge to calculate the formula we found for this graph, like this:

$y = (-1/2)x + 1$

Knowing that the general formula for writing make slope-intercept form is;

$y - y_1 = m(x - x_1)$

From the question, we know that:

• $m = -1/2$

• $(x_1,y_1) = (10,-4)$

Put the number to the formula:

$y - y_1 = m(x - x_1)\\y - (-4) = -1/2(x - 10)\\y + 4 = -1/2 (x - 10)\\y + 4 = (-1/2)x + 5\\y = (-1/2)x + 1$
