The constant of proportionality is 12

<h3>Constant of proportionality</h3>

The slope of the graph is equivalent to the constant of proportionality

The formula for calculating the slope is given as:

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

Using the coordinate points (5, 60) and (3, 36)

Substitute the given parameters into the equation:

m =\frac{36-60}{3-5}\\m =\frac{24}{2}\\ m = 12

Hence the constant of proportionality is 12

Two parallel lines are crossed by a transversal.
patriot [66]

Answer:

C. m=102

Step-by-step explanation:

We have been given an image of two parallel lines crossed by a transversal. We are asked to find the measure of m.

We can see that angle that measure 78 degrees and angle m are consecutive interior angles.

Since we know that consecutive interior angles are supplementary, so we can set an equation to find the measure of m as:

78^{\circ}+m^{\circ}=180^{\circ}

78^{\circ}-78^{\circ}+m^{\circ}=180^{\circ}-78^{\circ}

m^{\circ}=102^{\circ}

Therefore, the value of m is 102 and option C is the correct choice.

Complete the equations of the line through (-8, - 2) and (-4, 6)​
JulsSmile [24]

Answer:

y = 2x + 14

Step-by-step explanation:

As we move from  (-8, - 2) to (-4, 6)​, x increases by 4 and y increases by 8.

Thus, the slope, m, equal to rise / run, is m = 8/4, or m = 2.

Use the slope-intercept form of the equatino of a straight line:

y = mx + b.  This becomes 6 = 2(-4) + b, or 6 = -8 + b.  Thus, b = 14, and the desired equation is y = 2x + 14.
