Do you mean convert it to sin so that it is the same? If so, take 90 degrees and subtract the 22 degrees of the cosine. That equals 68 degrees so the sine equivalent to cos(22) is sin(68).

Which set of points would result in a slope of 1/4

8090 [49]

Answer:

C) ( 8,2) and (4,1)

The slope of the line

$m = \frac{1}{4}$

Step-by-step explanation:

Explanation:-

Given that the set of points ( 8,2) and (4,1)

ThesSlope of the line

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

$m = \frac{1-2 }{4-8 }= \frac{-1}{-4} = \frac{1}{4}$

The slope of the line

$m = \frac{1}{4}$

Graph the line that contains the point (-2,-4) and has a slope of 1/4

mixer [17]

Answer:

y = 1/4x - 7/2

Step-by-step explanation:

To answer this question, we have to use point-slope form:

y - y1 = m(x - x1)

Substitute the numbers into the variables:

y - (-4) = 1/4(x - (-2))

y + 4 = 1/4(x + 2)

y + 4 = 1/4x + 1/2

y = 1/4x - 7/2

To verify your answer, simply substitute the values into your equation:

-4 = 1/4(-2) - 7/2

-4 = -1/2 - 7/2

-4 = -8/2

-4 = -4
