how do you graph c =40t+ 250

250 is the y-intercept and 40 is the slope of the line.

To graph the equation c = 40t + 250, you can follow these steps:

1. Choose a range of values for t that you want to plot on the x-axis. For example, you can select a range from -10 to 10.

2. Substitute these values of t into the equation to calculate the corresponding values of c. For example, for t = -10, plug it into the equation: c = 40(-10) + 250 = -400 + 250 = -150. Repeat this process for each value of t within your chosen range.

3. Once you have the values of t and c, plot them on a coordinate plane. Place t values on the x-axis and the corresponding c values on the y-axis.

4. Connect the plotted points with a straight line to represent the graph of the equation c = 40t + 250. If your points are linear (fall in a straight line), you can draw a straight line through them. Otherwise, you may need to use a curve-fitting method to determine the shape of the graph.

Remember to label the axes and title the graph appropriately to provide clarity.

Note: When interpreting the graph, t usually represents time, and c typically represents a variable that depends on time.
