Answer:
y - 6 = -7(x + 8)
Step-by-step explanation:
Slope: m = (y2-y1)/(x2-x1) = (6 - -1)/(-8 - -7) = (6 + 1)/(-8 + 7) = 7/-1 = -7
Point-slope form: y - 6 = -7(x - -8)
=> y - 6 = -7(x + 8)
Answer:
480
Step-by-step explanation:
We can set up a proportion:
#students that eat carrots / #students surveyed=#students that eat carrots / #students surveyed
x will equal the number of students in Sarah's school who eat carrots.
30/50 = x/800
We can simplify
3/5=x/800
We cross multiply
5x=3*800
5x=2400
x=480
Hope this helps!
