Pick three 'easy' values for x and then solve for y.
Also, the y intercept occurs when the value for x is zero.
y=%283%2F2%29x%2B3+
let x = 0
y=%283%2F2%29%2A0%2B3+
y=3
y intercept and one point is (0,3)
let x = 1
y=%283%2F2%29x%2B3+
y=%283%2F2%29%2A1%2B3+
y+=+%283%2F2%29+%2B+3
y+=+9%2F2
Another point is (1, 9/2)
Let x = -1
y=%283%2F2%29x%2B3+
y+=+%283%2F2%29+%2A+%28-1%29+%2B+3
y+=+-%283%2F2%29+%2B+3
y+=+3%2F2
Third point is (-1, 3/2)

Hi,
y=%283%2F2%29x%2B3+ This is in the slope-intecept for y = mx + b where m is the slope and b the y-intercept(value of y where the line crosses the x-axis. Pt(0,3) a point on this line.

Use a t-table to find three sets of points
