You are looking for the slope and y intercept to complete the equation of the line.
The equation of a line is in something called slope intercept form. That looks like y = mx + b. m represents the slope (measure of how steep a line is, and in which direction it is going) and b represents the y intercept (y coordinate when x = 0). You need to find the slope and y intercept to complete the equation.
First, find the slope. The formula for slope is: m = (y2 - y1)/(x2 - x1) where m is the slope and (x1, y1) and (x2, y2) are points.
Pick any two points on the graph. I will use (-2, 0) and (0, 4). Now use these values to find the slope.
m = (4-0)/(0+2) = 4/2
m = 2
m = 2 means that for every two units the line goes up on the y axis, it moves one to the right on the x axis. 2 will go in your first box.
Now find the y intercept. The y intercept is where the line crosses the y axis - it is the y coordinate when x = 0. Here when x = 0, y = 4, so your y intercept is at 4. 4 goes into your second box.
The equation is y = 2x + 4
Answer:
Approx.3.6
Step-by-step explanation:
To find distance you need to use this formula:
d=sqrt of (x2-x1)+(y2-y1)
sqrt of(4-2) sqr+(10-7)sqr
sqrt of 2^2+3^2
sqrt of(4+9)
sqrt of (13)
approx.3.6
Answer:
see below
Step-by-step explanation:
Equilibrium quantity means the quantity supplied at a given price is equal to the quantity demanded at that price. To find it, look for the line in the table where quantities are equal. That line tells you the equilibrium price as well as quantity.
_____
On a graph, it is the point where supply and demand curves intersect (quantities are the same at the corresponding price).
F(x) = 36.77e^(-0.72x)
log f(x) = log36.77e^(-0.72x)
log f(x) = log 36.77 + log e^(-0.72x)
log f(x) = 3.6 + (-0.72x)log e
log f(x) = 3.6 - 0.72x
0.72x = 3.6 - log f(x)
x = 5 - 1.39 log f(x)
