Answer:
y = (-2/3)x - 1/3
Step-by-step explanation:
Find the equation of the line through the two points (-2, 1) and (1, -1).
As we increase x from -2 to 1 (an increase of 3), y decreases from 1 to -1 (a decrease of 2).
Thus, the slope of this line is m = rise / run = -2/3.
Using the slope-intercept formula y = mx + b, and substituting the givens m = -2/3, x = -2 and y = 1, we get:
1 = (-2/3)(-2) + b, or
1 = 4/3 + b, or 3/3 = 4/3 + b.
Then b must be 3/3 - 4/3, or -1/3, and the equation of the line is then
y = (-2/3)x - 1/3
Answer:
b

Answer:
Between 85 and 100
Step-by-step explanation:
Getting this will get the average between the required numbers since the average of 83 and 87 is 85, getting 85 will keep the answer at 85 and getting 100 will get the average at 90.

The answer is 3.5 inches for K12 test
All i did was see what coud make 49 feet.
since 1 inch = 14 feet then i did 3 x 14 which got 42.
