really need help. dont understand Given the points (2, 3) and (6, 8), write the point-slope form of the equation. A. y - 3 = x - 2 B. y - 3 = 5/4 (x - 2) C. y - 8 = 4/5 (x - 6)

    Do you know what point slope form is?

    Start by finding the slope between the two points: (2, 3) and (6, 8)

    Once you have the slope between the two points, use of the points and the point slope formula to create the proper equatioo.

    Subbtract the y-values and then subtract the x values. Then divide the resultant y values over the x values.

    (2, 3) and (6, 8), the y values are 8 and 3. the x values are 6 and 2. So 8-3=5 and 6-2=4. Now divide 5/4... This is your slope.

    the slope is 5/4 or do i divide that first then i will have the slope?

    5/4 is the slope

    now use the formula y-y1=m(x-x1). Replace m with the slope that you just found. and x1,y1 with one of teh coordinate points that were give.

    y-y1=m(x-x1). So replace m with 5/4.. This will look like y-y1=5/4(x-x1). Now say you chose to use the point (2, 3). This will look like y-3=5/4(x-2) If you were to use the point (6, 8), you will get something like y-8=5/4(x-6) both y-8=5/4(x-6) and y-3=5/4(x-2) are the same answers. It just will take some math to work them around to notice that.

    so it could be either one of those answers?

    But look what choices you have in the multiple choice. The only one that matches that is B: y-3=5/4(x-2)
