Question 38355
<pre><font size = 4><b>Graph the line with slope 2 that passes through (1,2)

Use the point-slope formula for the equation of the line that
passes through (x<sub>1</sub>,y<sub>1</sub>) with slope = m:

                y - y<sub>1</sub> = m(x - x<sub>1</sub>)

(x<sub>1</sub>,y<sub>1</sub>) = (1,2) and m = 2

                 y - 2 = 2(x - 1)
                 
                 y - 2 = 2x - 2

                     y = 2x

To graph it, plot the given point (1,2)

Then find a couple more points. Choose say x = 0, then y = 2(0) = 0,
so plot (0,0)

Then choose say x = -2, then y = 2(-2) = -4 so plot (-2,-4)

Then draw a straight line through them and you have

{{{ graph( 300, 300, -5, 5, -5, 5, 2*x) }}}
