Question
The equation y = 3 x - 22 represents the decline in the stock market. What are the slope and the y-intercept of the line?
- m = -3, b = 4 = 22
- m = 3, b = -22
Hint:
In this question we have to find slope and y- intercept from the given equation. For this we have to first compute the equation in the slope intercept form i.e. y= mx+ b, m is the slope and b is the y intercept . Given equation is already in the required format so we can identify both by looking at the equation.
The correct answer is: m = 3, b = -22
Given equation,
y = 3 x - 22
The equation given is in the slope intercept form i.e. y=mx+ b, m is the slope and b is y intercept
So, slope =3 and y intercept =-22
