Slope and intercept are two key concepts in numeracy that help you understand how variables change in relation to each other. They are often used to model real-world scenarios, such as how the ...

Use graphs, charts, or diagrams to show how your linear equation fits your data and how slope and intercept affect the shape and position of the line. Make sure your visuals are clear, accurate ...

Choose two coordinates on the line. Here (1, 4) and (3, 10) are used. Draw a triangle showing the horizontal movement to the right and the vertical movement up.

How to Find the Y-Intercept of a Line of a Graph in Excel on a Mac. Microsoft's Excel software for Mac can execute a number of statistical functions, including finding the y-intercept of the line ...

The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b. This calculation ...

Plotting linear graphs Going from rule to graph. To sketch a linear graph from a rule, determine two points that satisfy the rule and connect them with a straight line. Two commonly used methods are: ...
