Aline contains the points (4, 2) and (0, -1). what is the equation of the line? show your work.

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept (0, b)

We have two points (4, 2) and (0, -1) → b = -1.

Calculate the slope:

Finally:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract
