Equation Of A Straight Line y=mx+c

This video tutorial explains how to find the equation of a straight line using the y=mx+c format, where m is the gradient and c is the y-intercept. It begins with a brief introduction to the concepts of gradient and y-intercept, followed by examples to illustrate these ideas. The video includes a practice problem to help viewers apply what they've learned. Finally, it summarizes the key points and hints at future topics, such as rearranging equations to fit the y=mx+c format.

What is the first step in finding the equation of a straight line?

• Identify the y-intercept

• Determine the gradient

• Find the x-intercept

• Calculate the slope

In the equation y = mx + c, what does 'm' represent?

• The y-intercept

• The x-intercept

• The gradient

• The constant term

What is the y-intercept in the equation y = 3x - 5?

• 0

• 3

• -5

• 5

How do you calculate the gradient using two points on a line?

• Add the x and y values

• Subtract the x-values

• Divide the rise by the run

• Multiply the y-values

What is the equation of a line with a gradient of 5 and a y-intercept of -4?

• y = -5x - 4

• y = -5x + 4

• y = 5x - 4

• y = 5x + 4
