Step 1
<u>Find the equation of the line</u>
we know that
the equation of the line in the slope-intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope
b is the y-intercept
in this problem we have
![m=0.2\\b=0.3](https://tex.z-dn.net/?f=m%3D0.2%5C%5Cb%3D0.3)
substitute the values
Step 2
<u>identify the coordinates of four points on the line</u>
we know that
if a point belongs to the line, then the point must satisfy the equation of the line.
Let's assume different values of x and then with the equation we will calculate the value of y
<u>case a)</u> For ![x=0](https://tex.z-dn.net/?f=x%3D0)
Substitute the value of x in the equation and find the value of y
The point A is ![(0,0.3)](https://tex.z-dn.net/?f=%280%2C0.3%29)
<u>case b)</u> For ![x=1](https://tex.z-dn.net/?f=x%3D1)
Substitute the value of x in the equation and find the value of y
The point B is ![(1,0.5)](https://tex.z-dn.net/?f=%281%2C0.5%29)
<u>case c)</u> For ![x=-1](https://tex.z-dn.net/?f=x%3D-1)
Substitute the value of x in the equation and find the value of y
The point C is ![(-1,0.1)](https://tex.z-dn.net/?f=%28-1%2C0.1%29)
<u>case d)</u> For ![x=2](https://tex.z-dn.net/?f=x%3D2)
Substitute the value of x in the equation and find the value of y
The point D is ![(2,0.7)](https://tex.z-dn.net/?f=%282%2C0.7%29)
