Question

Write the equation of line AB , in slope-intercept form, given the points A(0, 5) and B(-5, -10). In your final answer, include all of your calculations.

Answer 1

Slope: $\dfrac{-10-5}{-5-0}=\dfrac{-15}{-5}=3$

The line passes through (0,5)[/tex], so the equation of the line is

$y-5=3(x-0)\implies y=3x+5$
