Step-by-step explanation:

the slope of a line is the ratio y/x.

that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.

so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).

therefore, the slope is

15/30 = 1/2

Answer:

Students collected

$18+90=108$ pounds of cans;
$340+108=448$ pounds of paper and cans combined in September and October.

Step-by-step explanation:

In September, the students collected 85 pounds of paper and 18 pounds of cans to recycle.

In October, their goal is to collect three times the amount of paper and five times the amount of cans they collected in September.

Hence, in October they collected

$85\times 3=255$ pounds of paper;
$18\times 5=90$ pounds of cans.

In total, they collected

$85+255=340$ pounds of paper;
$18+90=108$ pounds of cans;
$340+108=448$ pounds of paper and cans combined in September and October.
