math - pls check!!!

Write an equation in point-slope form for the line that passes through one of the following pairs of points (you may choose the pair you want to work with). Then, use the same set of points to write the equation in standard form and again in slope-intercept form.

(5, 1) and (-3, 4).
The formula for it is: slope = rise/run
slope = 4 – 1 / -3 -5 = 3/-8
-3/8 is the slope.

Point slope form
y - 1 = -3 (x - 5)/8

Slope intercept form
y - 1 = -3x/8 + 15/8
y = -3x/8 + 23/8

Standard form
8y = -3x + 23

is this ok? pls help asap! thanks

    looks good, except for the standard form. That would be

    3x + 8y = 23

    thank you Steven!:)
