What Is 'y = mx + c'
This lesson covers:
- What we mean by 𝑦 = 𝑚𝑥 + 𝑐
- 𝑚 is the gradient
- 𝑐 is the y-intercept
What does the 𝑚 in 𝑦 = 𝑚𝑥 + 𝑐 represent?
The 𝒚-intercept
The 𝒚 value of a coordinate
The gradient
The 𝒙 value of a coordinate
|
What does the 𝑐 in 𝑦 = 𝑚𝑥 + 𝑐 represent?
The 𝒚 value of a coordinate
The 𝒚-intercept
The 𝒙 value of a coordinate
The gradient

Rearrange the equation 6𝑥 + 3𝑦 = 15 into the form 𝑦 = 𝑚𝑥 + 𝑐.
𝑦 = - 6𝑥 + 15
𝑦 = 2𝑥 + 5
𝑦 = 5 - 2𝑥
𝑦 = -2𝑥 + 5

Rearrange the equation 2𝑦 - 16 = 4x into the form 𝑦 = 𝑚𝑥 + 𝑐.
𝑦 = - 6𝑥 + 15
𝑦 = 2𝑥 + 5
𝑦 = 5 - 2𝑥
y = 2𝑥 + 8
