Answer:

y=2x+2

Step-by-step explanation:

The y-intercept, or b, is 2 because the line intersects on the y-axis at (0,2)

To figure out slope, or m, it is the change in y over the change in x or rise over run.

You subtract the y-coordinates

-6-6 = -12

Then you subtract the x-coordinates

-4-2 = -6

You divide the two (the change in y over the change in x)

-12/-6 = 2

Your slope, or m, is 2 or 2/1

You then plug the slope and y-intercept into slope-intercept form (y=mx+b) to receive

y=2x+2 or y=(2/1)x+2

Slope-Intercept Find “y” alone 2( y - 3 ) = 10x + 4

Anettt [7]

Answer: y = 5x + 5

Step-by-step explanation: Okay follow these steps to get y alone.

2 ( y - 3 ) = 10x + 4

2y - 6 = 10x + 4

2y = 10x + 10

y = 10/2x + 10/2

y = 5x + 5

A group of cyclists went bike riding during a 7-day vacation. They biked 131 miles in the first three days. By the end of their

Nezavi [6.7K]

Answer: 156 miles

Step-by-step explanation:

Given, A group of cyclists went bike riding during a 7-day vacation.

Total distance they biked in first three days = 131 miles

Total distance they biked by the end of the vacation ( i.e. in 7 days ) = 287 miles

Then, the total distance they biked in last four days would be=

(Total distance they biked in 7 days ) - (Total distance they biked in first 3 days )

= 287 - 131 miles

= 156 miles

Hence, they biked 156 miles in last 4 days.
