Unit 0 algebra review functions graphing linear equations

1 answer:

3 0

Linear Equations:

y = mx + b

The y will of course, be the y coordinate

The m, would be the slope

X, the x coordinate

B, the y intercept

I'm not really sure what your question is, but to graph these, first put a dot at the y intercept, or if there is none, just 0. Then, take the slope, and place a point accordingly, for example, if the slope was 1, then the line would move up one unit per every x coordinate, if that makes any sense. And then, connect the two, and draw the line.

Did that make any sense?

Answer:

This really isn't a question. I can help you out with writing one.

John randomly selected 45% of seventh grade students in his school and asked them what their favorite time to play sports was. Of the students surveyed, 51 prefer to play sports after school. Based on this data, what is the most reasonable prediction of seventh graders in his entire grade?

Step-by-step explanation:

To answer my question, you would set up a proportion.

$\frac{9}{20} = \frac{51}{x}$ <-- the answer to that question will will be 113.

Answer:

y=-x-2

Step-by-step explanation:

To find the slope of the line, you can use the slope formula. I did this with (-3,1) and (2,-4) to get: (1+4)/(-3-2). This ends up as -5/5, which simplifies to -1.

next I plugged in the slope and one point into the line equation: y=mx+b. I plugged in (-4)=(-1)(2)+b. This equated to b=-2.

Check Work:

The equation -4=(-1)(2)-2 is true

The equation 1=(-1)(-3)-2 is true

Answer:

The amount of markup is 88 dollars.

Step-by-step explanation:

Given that the whole sale price of bicycle is: $400

$P = \$400$

Mark up is the profit that the seller of the product makes after selling the product more in price more than its cost or buying price.

Given that mark up percentage is 22%

It can be written mathematically as:

$Mark\ up = 22\%\ of\ Price\\Mark\ up = 0.22 * P\\Mark\ up = 0.22 * 400\\= \$88$

Hence,

The amount of markup is 88 dollars.
