Graph this line using slope
Slope = (y2-y1)/ (x2-x1)
y = m x +b
the slope is m
The y-intercept is (0, b)
_____________________
y = 2x +4 (yellow line)
The slope = 2 = 2/1 = (y2-y1)/ (x2-x1)
The y-intercept is (0, 4)
x= 0
y = 4
First draw the point (0, 4)
x= 0
y = 4
- Since the slope is 2 = variation in y / variation in x
From (0,4) the next point could be 1 more in x and 2 more in y (1, 6)
To continue
From (1,6) the next point could be 1 more in x and 2 more in y (2, 8)
From (2,8) the next point could be 1 more in x and 2 more in y (3, 10)
From (3,10) the next point could be 1 more in x and 2 more in y (4, 12)
___________________________________________
You only have the positive part so you won't need this
From (0,4) the next point could be 1 less in x and 2 less in y (-1, 2)
To continue
From (-1, 2) the next point could be 1 less in x and 2 less in y (-2, 0)
