<h3>Answer:   cos(Q) = 5/13</h3>

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

Work Shown:

The triangles are similar, which means the corresponding angles are congruent. In this case, we can say angle K = angle Q. Note how K and Q are the second letters of JKL and PQR respectively. The order matters.

Because angle K = angle Q, we can use information from triangle JKL to get information about triangle PQR.

We can say the following:

cos(angle) = adjacent/hypotenuse

cos(K) = LK/JK

cos(K) = 5/13

cos(Q) = 5/13 ... plug in K = Q

Y=-1/5 x -3 please help me
hammer [34]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following equation:

y = - \frac {1} {5} x-3

So we have to:

The slope is:m = - \frac {1} {5}

The cut-off point with the y axis is:b = -3

Answer:

The slope is: m =- \frac {1} {5}

The cut-off point with the y axis is: b = -3
