Concepts covered:equation of a straight line, y = mx + c, gradient, y-intercept, graph

The video explains how to determine the equation of a straight line using the formula y = mx + c, where m represents the gradient and c is the y-intercept. It demonstrates finding the gradient and y-intercept from a graph and substituting them into the equation to obtain the line's equation.

Question 1

What does 'c' represent in y = mx + c?

Question 2

What is the equation if m = -3 and c = 2?

Question 3

How do you calculate the gradient of a line?

Question 4

What is the equation if m = 1/4 and c = -3?

Question 5

If a line crosses the y-axis at 2, what is c?

Question 6

What is the y-intercept if the line crosses at -3?
