Answer:
My estimate would probably be y = 2/3 x + 10
Step-by-step explanation:
Remember that the formula for slope-intercept form is y=mx+b. Where m is slope and b is y-intercept.
First lets find slope, which is presented as rise/run. (rise is movement up and down and run is movement left and right).
Looking at the graph, we can estimate that the first point is at (20,25) and the second one next to it is at (35,35). Now to find slope quick and easy, we'll use this formula ⤵⤵⤵
[tex] \frac{y _{2} - y _{1}}{x _{2} - x _{1} } [/tex]
(Hopefully you can see it)
35 - 25 = 10
35 - 20 = 15
Slope = 10/15 or 2/3 (because 10÷5=2 and 15÷5=3)
Now we can use the slope to help us find the y-intercept.
Rather than going up 2 units and to the right 3 units, we'll do the opposite by going down 2 units and to the left 3, until we cross the y-axis.
With this in mind the y-intercept is about (0,10).
So to put it together, it is y = 2/3 x + 10.
Hope this helps :)
Since there was a bit of estimation involved, I'm sorry in advanced if it's wrong.
