The slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.

Step-by-step explanation:

If the line is passing through two points (x1, y1) and (X2, y2). The slope (m) can be calculated using following formula.

m = \frac{y2-y1}{x2-x1}

In this case,

x1  = 5

x2 = 7

y1  = 80

y2 =  65

By putting the values in formula, we get

m = \frac{(65-80)}{7-5}

m = \frac{(-15)}{2}

or

m = -7.5

Therefore, the slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.

True [87]

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be parallel, they need to have the same slope.

To find the slope (m), use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}      And plug in the two points

(-2, 7) = (x₁, y₁)

(4, -5) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-5-7}{4-(-2)}   (two negative signs cancel each other out and become positive)

m=\frac{-5-7}{4+2}

m=\frac{-12}{6}     Simplify the fraction

m = -2        

The slope is -2, so the parallel line's slope is also -2.

Solve with a system of equations: Two angles are supplementary if the sum of their measures are 180 degrees. If one is 90 degree
julsineya [31]

Answer:

  The measures of the angles are 150° and 30°.

Step-by-step explanation:

Let x and y represent the measures of the angles, with x representing the larger angle.

  x + y = 180 . . . . . . the two angles are supplementary

  x = 90 + 2y . . . . . one is 90° more than twice the other

___

Substituting the expression given by the second equation into the first, we have ...

  (90 +2y) +y = 180

  3y = 90 . . . . . . . . . . collect terms, subtract 90

  y = 30 . . . . . . . . . . . divide by the coefficient of y

  x = 180 -y = 150

The measures of the angles are 150° and 30°.
