Write the slope-intercept form of the equation of each line

slope intercept form- y=mx+b

m=slope

b=y-intercept

how to find slope= rise/run

how to fine y-intercept= go straight down the y axis (up and down in the center of the graph) until you come across a point

slope=3

y-intercept=-1

answer= 3x-1

If you would like to know about how far does a car travel in 7.1 seconds, you can calculate this using the following steps:

51.3 feet ... 1 second
x feet = ? ... 7.1 seconds

51.3 * 7.1 = x * 1
x = 51.3 * 7.1
x = 364.23 feet

The correct result would be 364.23 feet in 7.1 seconds.
