Rearranging Line Equations y = mx + c

The video tutorial explains how to rearrange straight line equations to find the gradient and y-intercept. It emphasizes the importance of converting equations into the Y = mX + c form for easier plotting and understanding. The tutorial includes examples and practice questions to reinforce learning. It concludes by highlighting the benefits of rearranging equations for quick identification of key line properties.

What is the purpose of rearranging straight line equations into the Y = mX + c format?

• To eliminate the y-intercept

• To easily identify the gradient and y-intercept

• To convert it into a quadratic equation

• To make the equation more complex

In the equation Y = 2X + 5, what does the number 2 represent?

• The y-intercept

• The x-intercept

• The gradient

• The constant term

After rearranging an equation, you find it in the form Y = 3X + 8. What is the gradient?

• 2

• 8

• 3

• 5

Why is the Y = mX + c format preferred for plotting graphs?

• It eliminates the need for coordinates

• It directly shows the gradient and y-intercept

• It makes the graph a circle

• It requires a table of values

What does the 'c' in the Y = mX + c equation represent?

• The gradient

• The x-coordinate

• The y-intercept

• The slope
