In ΔNOP, \overline{NP} NP is extended through point P to point Q, \text{m}\angle OPQ = (9x-19)^{\circ}m∠OPQ=(9x−19) ∘ , \text{m}

\angle PNO = (2x+5)^{\circ}m∠PNO=(2x+5) ∘ , and \text{m}\angle NOP = (3x+16)^{\circ}m∠NOP=(3x+16) ∘ . Find \text{m}\angle NOP.M∠NOP.

Answer:

To find the measure of angle OPQ, we have two equations...

y+5x-17=180 because angles OPN and OPQ are supplementary...

AND

x+17+2x-4+y=180 because the total degrees of a triangle must add up to 180.

The equations...

5x+y=197

3x+y=167

solce the system of equations...

x=15

y=122

Since we wanted to solve for y, 122 is the answer.

The measure of angle OPQ is 122.

Answer:

y = 2/3x + 4

Step-by-step explanation:

Slope-intercept form of a line:

  • y = mx + b
  • where m = slope and b = y-intercept

To find the equation of a line, we need two points that the line passes through.  

We can use the x-intercept and y-intercept of the line: (-6,0) and (0,4), respectively.

Find the slope of the line using these two points:

  • Slope formula: \displaystyle \bf  \frac{y_2-y_1}{x_2-x_1}

Plug the two points into the formula.

  • \displaystyle \frac{4-0}{0-(-6)}

Subtract and simplify this fraction.

  • \displaystyle \frac{4}{6} =\frac{2}{3}

The slope of this line is m = 2/3.

Now we can look at the graph to determine the y-intercept of this line; the line intersects the y-axis at (0,4) so the constant b = 4.

We can use the slope, m, and the y-intercept, b, and substitute these values into the slope-intercept form of a line.

  • y = 2/3x + 4

The equation of the line is y = 2/3x + 4.
