What is the slope intercept equation of the line below
shtirl [24]

Answer:

y = 2x - 3

Step-by-step explanation:

Step 1: Remember the equation

The slope intercept form is y = mx + b where m is the slope and b is the y-intercept

Step 2: Solve

We can see the y-intercept(where the line crosses the y axis) is at y = -3

We know slope is \frac{rise}{run} so we can see for every 1 square it moves right it moves 2 up so the slope would be \frac{2}{1}or 2

Plug what we know into the equation

y=2x-3

Step 3: Therefore Statement

Therefore the equation of the line shown below is y = 2x - 3

A company making tires for bikes is concerned about the exact width of their cyclocross tires. The company has a lower specifica
deff fn [24]

Answer:

For this process, the capability index is 0.4444

Step-by-step explanation:

Given the data in the question;

Lower specification limit = 22.8 mm

Upper specification limit = 23.2 mm

The standard deviation σ = 0.15 mm

Mean μ = 23

capability index Cpk = ?

Now, Using the formula;

Cpk = min{ [(USL - μ)/3σ], [(μ - LSL)/3σ]

where USL is the Upper specification limit, LSL is the Lower specification limit, σ is the standard deviation, μ is the mean

so we substitute

Cpk = min{ [(23.2 - 23 )/(3×0.15)], [(23 - 22.8)/(3×0.15)] }

Cpk = min{ [0.2 / 0.45 ], [0.2 / 0.45] }

Cpk = min{ [ 0.4444 ], [0.4444] }

Therefore, for this process, the capability index is 0.4444

Identifying Slope and y-Intercept of a Line
Ira Lisetskai [31]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

y = 1 - 3x = -3x + 1

slope = -3

y-intercept at 1

y = 3x - 1

slope = 3

y-intercept at -1

x - 3 = y → y = 1x - 3

slope = 1

y-intercept at -3

x + 3 = y → y = 1x + 3

slope = 1

y-intercept at 3
