Slope = 0.2 and y-intercept = 0.3
The slope intercept form of line is
y=mx + b where m is the slope and b is the y intercept
So equation becomes y = 0.2 x + 0.3
To find coordinates of 4 points , we plug in some number for x and find out y
x y = 0.2 x + 0.3
0 y = 0.2 (0) + 0.3= 0.3
1 y = 0.2 (1) + 0.3= 0.5
2 y = 0.2 (2) + 0.3= 0.7
3 y = 0.2 (3) + 0.3= 0.9
Four coordinates are (0,0.3) (1,0.5) (2,0.7) (3,0.9)
