Find the value of y so that the line passing through the two point has the given slope.

(2,y) (4,5) m=5 (m=slope)

how do you do this?

  • Algebra -

    (5-y) / (4-2) = 5

    solve for y

  • Algebra -

    I know that I'm suppose to find the y, but I don't know how.

  • Algebra -

    (5-y) / 2 = 5
    multiply both sides by 2
    5 - y = 10
    subtract 5 from both sides
    -y = 5
    multiply both sides by -1
    y = -5
