The slope-intercept form of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points from the graph (-4, -1) and (0, 3) → b = 3.

Substitute:

$m=\dfrac{3-(-1)}{0-(-4)}=\dfrac{4}{4}=1$

<h3>Answer: y = 1x + 3 → y = x + 3</h3>

Cheryl solved a problem: 84 ÷ 0.01 = 8,400.

Alexandra [31]

Answer:

Cheryl is correct.

Step-by-step explanation:

Cheryl solved a problem : 84 ÷ 0.01 = 8,400.

This is absolutely right.

When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.

To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.

$\frac{84\times 10}{0.01\times 10}$ = $\frac{840}{0.1}$

to make divisor a whole number we will again multiply both the numbers by 10.

$\frac{840\times 10}{0.1\times 10}$ = $\frac{8400}{1}$ = 8,400

Now answer would be 8400.

Therefore, Cheryl is correct.

a box half full of apples weighs 40kg and the same box one fifth full weighs 22kg. what does the box weigh when empty?

likoan [24]

So in order to answer your question we calculate 40 - 22 wich gives us the answer of 18, so now we can say that 4/5 of apples weight 18 so now 18 / 4 = 4,5; 4,5 * 5 = 22,5 wich is the weight of apples you can put in the box, to know the answer we deduct the greatest weight of apples only from the weight of the box with those apples so, 40 - 22,5 = 17,5
so the answer to your question is 17,5
