Slope formula
m = y₂- y₁/ x₂- x₁
m = 4 - (- 3) / 2 - 2
m = 4 + 3 / 0
m = 7 / 0
Slope is undefined.

it is just a vertical line.
See, for the first one when x = 2, y = -3
for the second one when x = 2, y = 4.
use the equation, Y2 - Y1/ X2 - X1
and you get 4 -(-3) / 2-2
so you will get 7/0. so thats not possible, so it's just a vertical line...
by the way that equation is used for finding the gradient. the 2 and 1 in the equation are actually in the subcript form. ask your teacher to explain it to you..

(2, -3) and (2, 4)
Writing this in slope-intercept form just isn't possible, because this is a vertical line. The equation of your line is
x = 2
How you can tell this is a vertical line is that they both share the same x value.

Use the formula m=(y2-y1)/(x2-x1) to find the slope of the line.
Now plug that into the formula y=mx+b, replace x and y with the numbers from one of your points, and solve for b.
You now have values for x and b, and y=mx+b is the equation of the line in slope-intercept form.

you need to get the slope
(y2 -y1) change in Y over
(x2 - x1) change in X
4 - (-3) = 7
2 - 2 = 0
This line has no slope (7/0 is not possible) it is verticle the only formula for the line is x = 2
