Question

What is the slope intercept of the equation y = -x + 12?

Answer 1

Answer: b) slope: -1, y-intercept 12

Explanation:

The equation here is in slope-intercept form (y=mx+b)

In slope-intercept form m is the slope and b is the y-intercept

m=-1 and b=12 so the answer is b

Answer 2

slope: -1, y-intercept: 12

Solution:

• The given equation is written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept.
• You can quickly identify the slope & y-intercept of a line whose equation is in slope-intercept form.
• The slope is the coefficient of x (the number before x) and the y-intercept is a constant added to/subtracted from the slope.
• Therefore, m is equivalent to -1, and b is equivalent to 12.
