Hello Professor and classmates
This is how I understand it, and please guide me to the correct answers if I’m wrong. The slope of the equation affects the graph of a linear equation by determining the steepness and direction of the line. The slope usually represents by (m), associates with the rise and the run. The rise refers to the (y) and is the change in going up or down. The run relates to the (x), and this is the change going from left or to the right. And this formula is referred to as rise over run. The type of test that we can use to test if an equation is a function is to do the vertical-line test. Where you draw vertical lines through the graph and if any of them intersect more than one time, this is not the graph function. And the difference between domain and range is that the domain is all the possible (x) values, and the range is all the possible (y) values. Thank you.

1. The slope of the equation affects the graph of a linear equation is as follows:
when the given line is of the form y=use an x-y chart with any choices of x (usually x= 0,1,2 is best)
2. when the given line is of the form
ð‘Žð‘¥+ð‘ð‘¦=â„‚
also known as standard form , graph using intercepts
3. when the given line is missing a variable, it is either horizontal or vertical
2) the type of test you can use to test if an equation is a function is as follows
to find the rise over run which we would use the formula m+rise over run = y over x =y2-y1over x2-x1 the difference between the domain and range is as follows:
to determine the domain from a graph look at where the graph extends from left to right
to determine the range of a graph look at where the graph extends vertically
