Step-by-step explanation:

7-5

-21-0

-2/21. the y intercept would be 5, considering the x is 0 on the first pair of coordinates. so y=-2/21x+5, or A

y = -2/21(x)+5

Step-by-step explanation:

We know that the formula to find the slope of an a line y = mx + b where m is the slope and b is the y-intercept.

The formula of slope is m = (y2-y1)/(x2-x1)

Using the two points given, we can find the slope:

m = (7-5)/(-21-0)

m = -2/21

b = 5 because (0,5) is the y-intercept

y = -2/21(x)+5

its 4 because 2 times 2 is 4, if you double the number two you get four

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
