What is the slope of the line passing through the points (2, 5) and (-1, -4)? show your work

Sati [7]

Answer:

We can solve this question using the slope equation which is y2-y1/x2-x1

If you use that formula and sub in the coordinates

-4 - 5 / -1-2

-9/-3

= 3

The slope should be 3/1

Answer:

a. Yes. The difference is common and equal to $1750

b. $1750

c. $20000 was initial investment

d. This is linear equation with start point of 20000 and slope of 1750:

y = 1750x + 20000

e. After another 10 years (on the top of 5 given) the investment will be:

y = 1750*15 + 20000 = $46250

f. After 20 years the value of investment will be:

y = 1750*20 + 20000 = $55000

When you multiply a function by -1, what is the effect on its graph?

Dafna1 [17]

9514 1404 393

Answer:

B. The graph flips over the x-axis

Step-by-step explanation:

When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.

The graph flips over the x-axis.

Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.
