What is the slope of a line represented by the equation 2y = × - 4?

IrinaVladis [17]

Y=mx+b is the slope intercept form where m=slope and b=y intercept

so
2y=x-4
divide both sides by 2
y=1/2x-2
slope is 1/2

Find the limit of the function by using direct substitution. limit as x approaches one of quantity x squared plus three x minus

ivann1987 [24]

Answer:

Limit = -1

Step-by-step explanation:

We are given the following function:

$x^2 + 3x -1$

We are to calculate the limit of this function as x approaches zero.

For that, we will use direct substitution method and substitute the x with 0 in the given function to calculate its limit as follows:

$x ^ 2 + 3 x - 1$

$( 0 ) ^ 2 + 3 ( 0 ) - 1 = - 1$

Therefore, the limit is -1.
