In function notation (f(x)=mx+b) m represents the slope and b represents the y-intercept.

In a straight horizontal line the slope is always 0. This cancels out the 'x' factor so you get f(x)=b.

To find b you simply look at where the line crosses the y-axis. in this case it crosses at 2.

When you plug in the y-intercept you get f(x)=2

India can paint 3 1/5 walls in one day. How many walls can she paint in 5 1/2 days?

Change the mixed numbers into fractions.

$3 \frac{1}{5}$
$3 * 5 = 15$
$15 + 1 = 16$
$3 \frac{1}{5} = \frac{16}{5}$

$5 \frac{1}{2}$
$5 * 2 = 10$
$10 + 1 = 11$
$5 \frac{1}{2} = \frac{11}{2}$

Multiply these fractions together:

$\frac{16}{5} * \frac{11}{2} = \frac{176}{10} 
$

Simplify the fraction.

$\frac{176}{10} / \frac{2}{2} = \frac{88}{5}$

$88 / 5 = 17 R3 = 17 \frac{3}{5}$

India can paint 17 and 3/5 walls in 5 and a half days.

The coordinate grid of the ordered pair is gotten from the combination of the y and X axis of the graph.

<h3>Finding of the ordered pair</h3>

Using the coordinates, an ordered pair for the given point is:

G = (4,3) because the 4 corresponds to the point in y axis and 3 on the X axis.

H= (10,8) because the 10 corresponds to the point in y axis and 8 on the X axis.

J= (6,4) because the 6 corresponds to the point in y axis and 4 on the X axis.

K= ( 2,1) because the 2 corresponds to the point in y axis and 1 on the X axis.

The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). Th

ziro4ka [17]

Answer:

67.49

Step-by-step explanation:

Let the number of HCF be x.

Let the cost be y.

You are given 2 points of a line: (15, 32.84) and (43, 79.04).

Now we find the equation of the line that passes through those points.

y - y1 = m(x - x1)

y - 32.84 = [(79.04 - 32.84)/(43 - 15)](x - 15)

y - 32.84 = (46.2/28)(x - 15)

y - 32.84 = 1.65(x - 15)

y = 1.65x - 24.75 + 32.84

y = 1.65x + 8.09

Now we let x = 36 and solve for y.

y = 1.65(36) + 8.09

y = 67.49
