What is the equation in point -slope form. of the line passing through (0, 5) and (-2,11)
Ksivusya [100]
First, you need to find the slope of the line. You can use this with the slope formula, \frac{y_{2} - y_{1}}{x_{2} - x_{1}}, where the x's and y's are the given coordinates.

\frac{y_{2} - y_{1}}{x_{2} - x_{1}}   Plug in the coordinates
\frac{11 - 5}{-2 - 0}   Subtract
\frac{6}{-2}   Divide
-3

Now, plug the slope (m) and one pair of coordinates, I'll use (-2, 11), into point-slope form, y - y_{1} = m (x - x_{1}).

y - y_{1} = m (x - x_{1})   Plug in the values
y - 11 = -3 (x - (-2)   Cancel out the double negative
y - 11 = -3 (x + 2)

Answer:

<STR = 38degrees

Step-by-step explanation:

Find the diagram attached

Complete Question:

In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?

Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y

y+y+104 = 180

2y = 180-104

2y = 76

y = 38degrees

Since <STR = y, hence the measure of <STR = 38degrees
