Final answer:
The equation in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Option b) y = mx + b is the correct answer.
Step-by-step explanation:
The equation in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
In the given options, option b) y = mx + b is the correct answer because it follows the slope-intercept form.
