What is the equation of the line that passes through the points (-2, 1) and (6, 3)?

earnstyle [38]

Answer:

y = $\frac{1}{4}$ x + $\frac{3}{2}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (- 2, 1 ) and (x₂, y₂ ) = (6, 3 )

m = $\frac{3-1}{6-(-2)}$ = $\frac{2}{6+2}$ = $\frac{2}{8}$ = $\frac{1}{4}$ , then

y = $\frac{1}{4}$ x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 3 ) , then

3 = $\frac{3}{2}$ + c ⇒ c = 3 - $\frac{3}{2}$ = $\frac{3}{2}$

y = $\frac{1}{4}$ x + $\frac{3}{2}$ ← equation of line

Anika [276]

The most likely answer is D) <span>"The date that the check is written is usually a few days before it is cashed. We record when it was cashed and you record when its written".

There is usually a delay between when you write someone a check (and record it in your ledger) and when that person cashes it (when the bank records it). </span>

babunello [35]

Answer:

No, we cannot conclude anything about 0.10

Yes, they have made the same decision.

Step-by-step explanation:

Consider the provided information.

Part (A)

They based this conclusion on a test using α = 0.05. Would they have made the same decision at α = 0.10

A significance level of 0.05 indicates a 5% risk of concluding that a difference exists

From the normal table the critical value is Z(0.05) = 1.645 and we accept null hypothesis.

If α = 0.1, the critical value is Z(0.1)=1.28

1.28 is less than 1.645.

Therefore, we cannot conclude anything about 0.10

Part (B)

α = 0.01, the critical value is Z(0.01)=2.33

The critical value of α = 0.05 is 1.645 which is less than 2.33,

So we would again reject the null hypothesis.

Hence, they have made the same decision.
