Answer:

Step-by-step explanation:

Take any 2 points on the graph,

(80, 90) & (40, 10)

Use the slope formula:

$\frac{y2-y1}{x2-x1}$

= (10-90)/(40-80)

= (-80)/(-40)

= 2

Hence, the slope is 2.

Tina is saving to buy a notebook computer. She has two options. The first option is to put $500 away initially and save $30 ever

Jlenok [28]

First option:
y=money saved
x=number of months

y=30x+500

Second option:

y=50x+200

We have this system of equations:

y=30x+500
y=50x+200

We can solve this system of equations by equalization method
30x+500=50x+200
30x-50x=200-500
-20x=-300
x=-300/-20
x=15

so;
y=30x+500
y=30(15)+500
y=450+500
y=950

Answer; after 15 months, she would save the same amount using either option, the amount saved in either option will be $950.
