How do you find the slope and y intercept of #y = 2x#?

Answer 1

See a solution process below:

This equation can be written in slope-intercept form. The slope-intercept form of a linear equation is: #y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept value.

#y = color(red)(2)x + color(blue)(0)#

Consequently:

The slope is: #color(red)(m = 2)#

The #y#-intercept is: #color(blue)(b = 0)# or #(0, color(blue)(0))#

In the equation ( y = 2x ), the slope is the coefficient of ( x ), which is ( 2 ), and the y-intercept is the point where the line intersects the y-axis, which in this case is ( 0 ). Therefore, the slope is ( 2 ) and the y-intercept is ( 0 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
