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 (x1,y1) with slope = m:
y - y1 = m(x - x1)
(x1,y1) = (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
