Writing equations in slope intercept form
Y = mX + b Slope or Rate of change Y intercept

4 5 Y = -⅘X - 3 The line has a negative trend
So the slope is - ⅘ Y The y intercept is at 0, -3 So the equation for the line is…… 4 X Y = -⅘X - 3 5

4 12 Y = ⅓X + 6 The line has a positive trend So the slope is ⁴⁄₁₂ = ⅓
The y intercept is at 0, 6 So the equation for the line is…… Y = ⅓X + 6

2 1 Y = 2X + 1 The line has a positive trend So the slope is ²⁄₁ = 2
The y intercept is at 0, 1 1 X So the equation for the line is…… Y = 2X + 1

2 3 Y = -⅔X - 1 The y intercept is at 0, -1
So the equation for the line is…… Y = -⅔X - 1 2 X 3 The line has a negative trend So the slope is - ⅔

Y = ½X + 6 Y = ½X + 0 Y = ½X - 4 Parallel lines will ALWAYS
Have the same slope Y = ½X + 0 X Y = ½X - 4

Y X Horizontal line Y = 2

Y Vertical line X = - 5 X

The line has a negative trend So the slope is The y intercept is at
So the equation for the line is…… X

The line has a positive trend So the slope is
Y X The line has a positive trend So the slope is The y intercept is at So the equation for the line is……

The line has a positive trend So the slope is
Y The y intercept is at X So the equation for the line is……

So the equation for the line is……
The y intercept is at Y So the equation for the line is…… X The line has a negative trend So the slope is
