Question

Solving the equation of the word problem presented in the Video, Example 54, Using slope–intercept form for graphing, which is located in the media section of Chapter 3, involves which two steps? (Points : 1)
Plot the x–intercept and then use the slope to find the next point.
Plot the y–intercept using the slope to find the next point.
Find the x– and y–intercepts to use as two points to connect and form a line.
Choose three arbitrary x values to use to find the corresponding y values.

Answer 1

Find the x– and y–intercepts to use as two points to connect and form a line

Answer 2

x-intercept is where y=0
y-intercept is where x=0

so, just plug in 0 for y or x and find the two intercepts. Then just connect them with a line. Done.
