Question

The equation of a line is y = 1.5x − 2. What are its slope and y-intercept?
A.
slope = 1.5 and y-intercept = -2
B.
slope = 1.5 and y-intercept = 2
C.
slope = 2 and y-intercept = 1.5
D.
slope = -2 and y-intercept = 1.5

Answer 1

This equation is written in slope intercept form, y=mx+b, with m being the slope and b being the y-intercept.

The slope of the line is 1.5 and the y-intercept is -2. The answer is A.

I hope this helps ;)

Answer 2

If the equation in slope-intercept form of a line is given as y = 1.5x - 2, the slope and y-intercept are:

A. slope = 1.5 and y-intercept = -2

Note the following:

• Equation of any straight line, in slope-intercept form is: y = mx + b
• The "b" represents the y-intercept
• The "m" represents the slope.

Therefore, given the equation of a line:

• y = 1.5x - 2

The slope = 1.5

The y-intercept = -2

In summary, if the equation in slope-intercept form of a line is given as y = 1.5x - 2, the slope and y-intercept are:

A. slope = 1.5 and y-intercept = -2
