Answer:

Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)
Hope it helps and let me know if you want me to elaborate.
Answer:
288
Step-by-step explanation:
If 52% studied French, then 48% didn't. The ratio of those who didn't to those who did is ...
(didn't study French)/312 = 48%/52% = 12/13
Then the number that didn't study French is ...
(didn't study French) = 312 × 12/13 = 288 . . . . . . multiply above by 312
288 students chose not to take French their Junior year.
Answer:
y=1/4x-1.5
Step-by-step explanation:
So, because the line is parallel, the slope is the same. Then, to get the y-int, you do b=y-mx with the point, so the equation is b=-1-(1/4)(2), then you multiply to get b=-1-(0.5), so your y-int is -1.5.
