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

The cost of 2 plates of spaghetti & 1 plate of salad is $27.50. The cost for 4 plates of spaghetti & 3 salads is $59.50.

k0ka [10]

2a+1b=27.50

4a+2b=59.50

Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.

Then plug b into one of the original equations and solve for a and you should get 10.75

So a plate of spaghetti is $10.75 and a salad is $6.
