Here's a graph of a linear function. Write the equation that describes that function.

Lerok [7]

The slope-intercept form of the graph is $y=\frac{1}{2} x+4$ .

Solution:

Let us take any point on the straight line.

Here, we take (–8, 0) and (0, 4).

Let us first find the slope of the line.

Slope of the line formula:

$$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$x_1=-8, y_1=0, x_2=0, y_2=4$

$$m=\frac{4-0}{0-(-8)}$

$$m=\frac{4}{8}$

$$m=\frac{1}{2}$

Slope-intercept form:

$y-y_1=m(x-x_1)$

$$y-0=\frac{1}{2} (x-(-8))$

$$y=\frac{1}{2} (x+8)$

$$y=\frac{1}{2} x+\frac{8}{2}$

$$y=\frac{1}{2} x+4$

Hence the slope-intercept form of the graph is $y=\frac{1}{2} x+4$ .

Answer:

The equation is: y = 15·x

Step-by-step explanation:

It is provided that at the Speedy Bike Works, 15 bicycles are produced each hour.

Consider the table below.

Number of Hours: 1 3 6 10

Number of Bicycles Produced: 15 45 90 150

Compute the ratio of number of bicycles produced and number of hours for every data above as follows:

$\text{1 hour}=\frac{15}{1}=15:1\\\\\text{3 hour}=\frac{45}{3}=\frac{15}{1}=15:1\\\\\text{6 hour}=\frac{90}{6}=\frac{15}{1}=15:1\\\\\text{10 hour}=\frac{150}{10}=\frac{15}{1}=15:1$

The ratio of the number of bicycles produced and number of hours is same for every data value.

Thus, the relationship between the number of bicycles produced and number of hours is proportional.

The equation for the relationship is:

y = 15·x

y = number of bicycles produced

x = number of hours
