How can you write the equation for a linear function if you know only two ordered pairs for the function?

Answers

Answer 1

1. m
2. One set of ordered pairs
3. b

To show why this is, I’m going to explain how to write the equation for a linear function with two random sets of ordered pairs - (1,0) and (5, 8).

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 two sets of points.

This is why #1 is m. M is the letter used when finding slope.

To find m, I plug in the two sets of ordered pairs.

m = (8-0)/(5-1)
m = 8/4
m = 2

An equation for a line (linear function) is written in something called slope-intercept form. It looks like y = mx + b. m is the slope and b is the y-intercept (number y equals when x = 0). If m = 3 and b = 1, the equation would be y = 3x + 1.

Here, you have just solved for m and know it equals 2. Plug that value in for m.

y = 2x + b

To solve for b, plug one ordered pair in for x and y. I will use (1,0)

0 = 2(1) + b
0 = 2 + b
-2 = b

Now that you know b = -2, plug that in for b.
y = 2x - 2. Now you have the equation fo the line.

Is x=2 a solution to 3x+5>10? Explain

Answers

Yes

To figure out if x = 2 is a solution, plug 2 in for x. If the left side is greater than 10, then x is a valid solution. If the left side is not greater than 10, than x is not a valid solution.

3x+5>10
3(2)+5>10
6+5>10
11>10

11 is actually greater than 10, so x=2 is a solution to this inequality

What is the slope of the line that passes through the points (0, -4)) and (-2, -1)

Answers

Answer:

Step-by-step explanation:

y = mx + b

m is the slope (what you want)

b is the y-intercept, which is the value of y when x = 0

Oh, right, we already have b, isn't that great!

Given point (0, -4), so b = -4

Point (-2, -1), where x = -2 and y = -1

-1 = -2m -4 (solve for m)

3 = -2m

m = -3/2

Check:

y = -3x/2 -4

y = -3(-2)/2 -4 -> should get y = -1

y = 3 -4 = -1

Yay, we have the answer!

The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.

For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.

Always True:

The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.

Always True:

The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.

Assume that the sum of an irrational number a and a rational number b is rational.

Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.

American Discounters:

149.49 - 30%

149.49 - (149.49 * 0.3) = 44.847

149.49 - 44.847 = 104.643

The Coffee Hut:

91.99 + 15%

91.99 + 13.8 = 105.79
