Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}

(5,3) (4,-3)

x_1   y_1    \\x_2  y_2\\\\

\frac{3 - (-3)}{4-5} =\frac{-6}{-1}  = 6

slope = 6

as for y-intercept use this method in the attachment

How many integers between 10 and 500 begin and end in 3?
hodyreva [135]

If from 0 - 10 there is 1 number ending in 3 (3) we'll aplly the same logic to 500.

Between 0-10 there is 3. Between 10 - 20 there is 13. Between 20-30 there is 23. Between 30-40 there is 33, etc.


If we divide 500 into 10 we get 50:

500 / 10 = 50


That means there are 50 groups of 10 in the number 500. If we know that every 10 numbers has 1 ending in 3, we multiply 1 by 50:

1 x 50 = 50

So, our conclusion is, that there are 50 numbers ending in 3 between 10 and 500.


Hope it helped,

Kaseem had 1/4 box of candy. He ate 1/2 of the candy. What fraction of the box did Kaseem eat? Show all work.
Harrizon [31]

Answer:

1/8

Step-by-step explanation:

If Beth had 1/4 a box of candy, and she ate 1/2 of the remaining candy, she would have 1/8 because the equation is calling for you to multiply 1/4 by 1/2 or divide 1/4 by 2. To multiply two fractions, you multiply straight across. When you do so, 1x1 equals 1 and 4x2 equals 8, leaving you with an answer of 1/8!
