I need help with numbers 1-4 please if someone could help me

laila [671]

You can use the slope formula or just calculate
$\frac{rise}{run}$
So for the first problem you run 3 units right and rise 5 units so
$\frac{rise}{run} = \frac{5}{3}$
2. Notice the y axis goes by 2 units.
$\frac{ - 10}{4} = \frac{ - 5}{4}$
3.
$\frac{0}{12} = 0$
4.
$\frac{2}{0} = undefined$
Please let me know if you have questions
