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.
Find the x– and y–intercepts to use as two points to connect and form a line
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.
To solve the equation of the word problem using slope-intercept form, you would typically follow these two steps:
1. Find the x- and y-intercepts to use as two points to connect and form a line. The x-intercept is the point where the line crosses the x-axis, and its y-coordinate is always 0. The y-intercept is the point where the line crosses the y-axis, and its x-coordinate is always 0. By determining these intercepts, you will have two points on the line.
2. Use the slope to find the next point. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope and b represents the y-intercept. The slope, m, indicates how steep the line is. You can use the slope to find the next point on the line by using the equation y = mx + b. Substitute the x-coordinate of the next point into the equation, and solve for y. This will give you the coordinates of the next point on the line.
Therefore, the correct answer to the question is: Find the x- and y-intercepts to use as two points to connect and form a line, and then use the slope to find the next point.
