Answer:
![y=\frac{4}{5}x+1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B5%7Dx%2B1)
Step-by-step explanation:
We are given the slope, and the y-intercept. So we can use the slope-intercept equation. Which is as follows:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
is the slope and
is the y-intercept (the value of
when
).
The information that we have is that the slope of the line is:
![m=\frac{4}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B4%7D%7B5%7D)
and that the line crosses the y-axis at (0, 1).
From this point we can find the y-intercept
, because b is the value of
when
.
And since the line passes through (0, 1) when
,
. Thus, the y-intercept is:
![b=1](https://tex.z-dn.net/?f=b%3D1)
substituting the values of the slope and the y-intercept into the equation:
![y=mx+b\\y=\frac{4}{5}x+1](https://tex.z-dn.net/?f=y%3Dmx%2Bb%5C%5Cy%3D%5Cfrac%7B4%7D%7B5%7Dx%2B1)
the answer is: ![y=\frac{4}{5}x+1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B5%7Dx%2B1)
