Question

Look at this graph. 100 70 0 10 20 30 40 50 60 70 80 90 100 What is the equation of the line in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form. Submit

Answer 1

In the form solope intercept we need to find the slope and the intercept, so we can see that the intercept in the graph and is:

`b=70`

now to find the slope we can use this equation:

`m=(y_2-y_1)/(x_2-x_1)`

and we replace ywo coordinates so I use ( 0,70) and ( 10,80) so the slope will be:

`m=(80-70)/(10-0)=(10)/(10)=1`

So the equation is:

`y=x+70`
