Answer:
5
Step-by-step explanation:
The equation 
is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format 
, such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,
The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation is given in the slope-intercept form, and the coefficient (
) equals (
), therefore the slope is ().

4 teaspoons of salt.
Step-by-step explanation:
2+2=4
We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. x = 0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y = -1
This can be expressed as an ordered pair as (-1, -1)
Answer:
Step-by-step explanation:
When you follow the curve from the left toward x=2, you wind up at the open circle at (2, 4). The limit from that direction is 4.
When you follow the curve from the right toward x=2, you wind up at the open circle at (2, -4). The limit from that direction is -4.
