Slope intercept form of an equation is:
y = mx + b
where m is the slope and b is the t intercept.

First you must determine the slope of the line. This is a ratio of how fast the line travels up or down vs how fast it is moving to the right. Another name for this is rise over run. The equation to find the slope is:
m = (y1 - y2) / (x1 - x2)

now to find b. We can plug in one of the points of the equation into our first equation along with the slope to get out b value.

So if our 2 points were (2, 3) and (3, 4) we could find slope intercept form like this:
m = (2 - 3) / (3 - 4)
m = -1 / -1
m = 1
Now taking point (2, 3)
3 = 1 * 2 + b
1 = b
Finally to plug our m and b into equation for answer:
y = 1x + 1
However, 1 * anything is redundant therefore:
y = x + 1

Ella and three friends run in a relay race that is 14 miles on each person runs equal parts of their race how many miles does ea

Lerok [7]

To find out how many miles does each person run, we can divide the total miles by 4 as each part is equal:

14÷4

=3.5miles

Each of them have to run 3.5 miles.

To prove the answer, we can multiply it by 4 to see if it is the original distance:

3.5 x 4

=14miles

Therefore 3.5 is the answer.
