depends on the equations, if eg, y=2x+3, slope is 2.

There is no equation. Just this question. Don't understand what they want.

The equation of a non-vertical line can be written in several forms.
The form that appears to be most common is
y = mx + b
If written in that form, the slope is m
e.g. for y = (2/3)x + 5 , the slope is 2/3. I did not find any points
If the equation is written in the form
Ax + By= C , the slope is - A/B
e.g.. for 5x + 8y = 11
the slope is -5/8
for 4x - 9y = 33, the slope is 4/9
