Question 320622: "What is the graph of the equation c= 20t+30"
Answer by nyc_function(2741)   (Show Source):
You can put this solution on YOUR website! Your graph will have points in the form (t,c).
STEPS:
1-select about 3 values for t (I chose t = 0...see below)
2-simplify the right side of the equation for each value selected in terms of t
3-When you find the value of t and c, plot each point (t,c) on the coordinate plane
4-Connect each point with a line
==================================
Let's say that t = 0
c = 20t + 30
c = 20(0) + 30
c = 0 + 30
c = 30
Your first point to plot is (0,30).
Can you find two more points and then follow the above steps?
Your function is a straight line. Can you do it now?
