Graph the equation y = 1/2x + 3

Find some graphing paper and graph away ...

i. e. Sub in x = 0 and find what y = ?

y = 1/2 (0) + 3

y = 3

So we know the coordinate (0,3)

When x = 4, y = ?

y = 1/2 (4) + 3

y = 4/2 + 3

y = 2 + 3

y = 5

So we know another coordinate (4, 5)

When x = - 4, y = ?

y = 1/2 (-4) + 3

y = - 4/2 + 3

y = - 2 + 3

y = 1

So we know another coordinate (-4, 1)

Putting it all together, the coordinates: (-4, 1), (0, 3) and (4, 5) should be plenty sufficient to graph and then draw a line of best fit connecting them.
