Graph this line using the slope and y-intercept: y = 1/9x + 4

1 answer:

8 0

If you don’t know how to graph slope intercept equations here’s a simple step by step way.

Tiny explanation for step 1:

In y= 1/9x + 4 (y= mx+b) the 4 (b) is the y-intercept. In y= 1/9x + 4 (y= mx+b) the 1/9 (m) is the slope.

1. So go to (0,0) and go 4 units up and circle the point (0,4) which is going to be your lines y-intercept. (the vertical line in a graph is the y-axis, all y-intercepts are on this axis.)

Quick explanation for step 2: Once you have this point (0,4) your going to now use the slope of the equation (which is 1/9). Slopes are in rise over run formate or in more simplistic terms the top number (this only works with fractions) is how many spaces you go up and the bottom is how many spaces you go to the right (this is a positive slope so I won’t explain for negatives).

2. At point (0,4) your y-intercept go 1 unit up and 9 units to the right. Continue this with the new point u made if room (draw an arrow at the end). Then go back to (0,4) and do the other side of the line. This time go down 1 unit and left 9 units from (0,4) your y-intercept.

Hope this was at least somewhat helpful and not completely confusing!

If -3m + 1 > 7, which of the following is a solution set for m?

Papessa [141]

ANSWER

m < -2

EXPLANATION

We want to find the solution set for m in:

$-3m+1>7$

First, collect like terms:

$\begin{gathered} -3m>7-1 \\ -3m>6 \end{gathered}$

Now, divide both sides by -3. When you divide an inequality by a negative number, the sign changes direction:

$\begin{gathered} \frac{-3m}{-3}>\frac{6}{-3} \\ m$

This means that all values of m must be less than -2.

None of the options contains the correct solution set.

Use the table of values to calculate the linear correlation coefficient r. X 4,53,86,162 Y 5,1,13,16

Zielflug [23.3K]

Okay so plug them in to get x and y so use 5 as x and 1 as y

If the Greatest Common Factor of L and M is 6, write the expression for the Least Common Multiple of these numbers.

zhuklara [117]

Answer:

$\frac{(L x M)}{6}$

Step-by-step explanation:

The greatest common factor is the greatest number that will divide two values. We have two values L and M. Each has numbers which multiply together to give the number. The highest value or most in common they share is 6. This is the GCF.

The least common multiple is the smallest positive number which is a multiple of the two. This means both L and M divide into it evenly.

We know L x M is a multiple because L and M will be factors of it. But we don't know its the least.

As an example if L= 42 and M = 60, they have GCF 6. We can multiply them to find a multiple 42 x 60 = 2520 but we don't know this is the smallest or least multiple we can find. If we divide by the GCF, 2520/6=420. Interestingly, 42 x 10 =420 and 60 x 7 =420. This means 420 is the least common multiple.

We can multiply (L x M) and then divide by the GCF of L & M to find the least common multiple.

$\frac{(L x M)}{6}$

There were 400 pieces of candy in all. If 60 pieces were chocolate, then what percent of the candy was chocolate.

Liono4ka [1.6K]

400 --- 100%
60 --- x%

x = 60/400 * 100 = 15% chocolate.
