Using Intercepts
What is the y-coordinate of the point where the graph intersects the y axis called?
Y-intercept
What does the letter m stand for in the equation y=mx+b
M = slope/rate of change
In ordered pairs, how do you know if it is a function or not?
Each x-value must be different
Find the slope: 2x- 4y=8
x=4
Write the equation in slope intercept form: slope=0, y intercept =-5
y=-5
What does the letter 'b' stand for in the slope-intercept formula? y=mx+b
Y-intercept or initial fee
In a table of x and y values, how do you determine if the table is a function or not?
Each x-value or input has only one output.
Find the slope of 3x+4y=24
-3/4
What is the slope-intercept form equation?
y=mx+b
In a mapping diagram, how do you determine function or not?
Each input has only one output
