Write an equation in slope-intercept form for the line with slope -4 and y-intercept -1

y=-4x-1

Step-by-step explanation:

slope = m

y-intercept =b

y=mx+b

y= -4x -1

y=-4x-1

Step-by-step explanation:

The slope-intercept form is as follows "y=mx+b"

In this case, m, your slope, is -4.

Your b-value, is the y-intercept, -1.

Therefore your equation is y=-4x-1

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
