Equation of the line passing through (7,5) and (1, 2)​
Trava [24]

Answer:

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

Step-by-step explanation:

Assuming this is a linear equation in the form of y = mx + b, we can first solve for the slope using \frac{y_2 - y_1}{x_2 - x_1}, for these points, the slope would be \frac{1}{2}. Now we plug in the points to get the equation:

plugging in (7,5), we get 5 = \frac{1}{2} ×7 + b

and solving for b, we get b = \frac{3}{2}

therefore, the equation of the line passing through (7,5) and (1,2) is y = \frac{1}{2}x + \frac{3}{2}.

hope this helps!

Problem 5

Apply the Law of Sines

s/sin(S) = r/sin(R)

s/sin(78) = 10/sin(48)

s = sin(78)*10/sin(48)

s = 13.162274

<h3>Answer:    13.162274 approximately</h3>

=============================================================

Problem 6

Use the Law of Sines here as well.

x/sin(X) = y/sin(Y)

x/sin(53) = 6/sin(22)

x = sin(53)*6/sin(22)

x = 12.791588

<h3>Answer:    12.791588 approximately</h3>
