Write an equation in slope-intercept form for the line that satisfies the following condition.
passes through (11, –15) and (16, 5)

  • algebra 2 -

    slope = (5 -(-15))/(16-11) = 20/5 = 4

    so the equation is y = 4x + b
    but (16,5) lies on it, then

    5 = 4(16) + b
    b =-59

    y = 4x - 59
