2 slope problems PLEASE help Write the equation of the line with a slope of -1/3 and passing through the point (6, -4). Write the equation of the line passing through the points (-6,1) and (-4,2).

    For the first equation, use the point slope formula and plug in the given data

    y+4=(-1/3)(x-6) ----->Now rearrange this if it is required. You can leave it like this since it is correct.

    And for the second part, find the slope between the two points: (-6,1) and (-4,2).. And use one of the points to form the equation.

    It would have helped if you would spell out the words. And no, it is not y=-1/3x-6. Instead it is y=-1/3x-2

    For the second part, can you find the slope between the two points?

    The slope would be 1/2. Now pick either point and write the equation.

    y-2=1/2(x+4)----> Now rearrange this and get y=1/2x+4

    ok thanks :) do you understand this problem : Write the equation of the line with an undefined slope, passing through the point (2, 5).

    I don't understand how u can write an undefined slope

    undefined slope means the line is vertical. Therefore, the equation for the line would be y=2

    wait, x=2.

    so you don't do anything with the 5?

    y=2 would be horizontal, so it would be x=2

    5 is a point above the 2. Only the first variable matters, which is 2.
