Question

Write an equation in slope-intercept form for the line that satisfies the following condition.

slope 2/5 and passes through (10, –20)

Answer 1

y = 2/5 x - 24.

Explanation:

We are given the slope and a point on the line so we use the point-slope form of the graph.

y - y1 = m(x - x1) so we have:

y - (-20) = 2/5(x - 10)

Converting to slope-intercept form:

y + 20 = 2/5x - 4

y = 2/5x - 4 - 20

y = 2/5 x - 24.
