Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form. y = 3x − 7 y = 3x − 5 y = 5x − 11
babymother [125]
Find the slope of the line first using \frac{y2 - y1}{x2 - x1}
(3, 4), (2, -1)
\frac{-1 - 4}{2 - 3}
\frac{-5}{-1} = 5

Now use y - y1 = m(x - x1) to make an equation in slope-intercept form. Plug the numbers into the formula.

y - (-1) = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11

The equation of the line in slope-intercept form would be y = 5x - 11.
