Consider the line that passes through the point (3, -6) and has a slope of 4.

Part 1: Write the equation of this line using point-slope form. (2 points)

Part 2: Using your equation from part 1, rewrite this equation in slope-intercept form. Make sure to show all of your work. (2 points)

Part 3: Using your equation from part 2, rewrite this equation in standard form. Make sure to show all of your work. (2 points)

    1) y + 6 = 4(x - 3)

    2) y + 6 = 4x - 12

    y = 4x - 18

    3) -4x + y = -18

    I hope this information was very helpful.

    point slope formula is y-y1=m(x-x1)

    m=slope

    so : y-(-6)=4(x-3)

    y+6=4x-12 now solve for y

    y=4x-18 (this is slope intercept form)

    -4x+y=-18 divide by -1

    4x-y=-18
