Problem
Hi, how do I graph linear functions on a graph using y = mx + b?
Solution
For this case we can conclude that m is the slope and represent the units that y increase for each increment of 1 unit on the x axis.
And b represent the value of the function when x=0
Example:
y = -2/3 x +4
m =-2/3
b=4
We can find the x intercept like this:
0= -2/3 x + 4
2/3 x = 4
x= 3*4/2= 6
Two important points (0,6) and (0,4) for the plot
And the graph would be:
