Slope-intercept from two points

Mathematics
1 answer:
neonofarm [45]3 years ago
3 0

Answer:

y=1/2x - 2

Step-by-step explanation:

The y-intercept is -2 and the slope of the line is 1/2. You can find the slope by using the rise over run method, which is the change in y over the change in x. In the points, x changed by +2, and y by +1, which is 1/2. Substitute that into the formula y=mx + b using one of the points to find the y-intercept, or b. You could use -4 = 1/2(-4) + b, solve for b, and you would get -2.

Graph the line with the equation

The graph of the linear equation can be seen in the image below.

<h3 /><h3>How to graph the linear equation?</h3>

Here we have the linear equation:

y = (2/5)*x - 6

To graph it, we just need to find two points on the line, and then connect them with a line.

To find the points we just evaluate in two values of x.

if x = 0.

y = (2/5)*0 - 6 = -6

Then we have the point (0, -6)

If x = 5.

y = (2/5)*5 - 6 = 2 - 6 = -4

Then we have the point (5, - 4)

Now we can graph these two points and connect them with a line. The graph of the line can be seen below.

A bike store rents bikes for $9 an hour in addition to a helmet rental fee of $15. If
wel

Answer:

4 hours

Step-by-step explanation:

First we need to subtract the one pay fee (the helmet rental fee, $15)

So 51 - 15 = 36

Then we need to divide 36 by the amount of money it costs for each hours to find how many hours he rented the bike

So 39/9 = 4
