In a linear equation, if the slope is 3 and the y-intercept is -2, what is the equation of the line?
y = 3x + 2
y = 3x - 2
y = -3x + 2
y = -3x - 2
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Here, m = 3 and b = -2, so the equation is y = 3x - 2.

Q: In a linear equation, if the slope is 3 and the y-intercept is -2, what is the equation of the line?
Solution: The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Here, m = 3 and b = -2, so the equation is y = 3x - 2.
Steps: 4
Step 1: Understand the slope-intercept form of a linear equation, which is y = mx + b.
Step 2: Identify the slope (m) and the y-intercept (b) from the question. Here, m = 3 and b = -2.
Step 3: Substitute the values of m and b into the equation. Replace m with 3 and b with -2.
