Answer:
The slope of the line is m = 2
Step-by-step explanation:
We can use the point-slope equation:
Where:
is the coordinate of the first point
is the coordinate of the second point
Here, we can use any pair of points. Let's chose
Using these points in our slope equation, we have:
Therefore the slope of the line is m = 2.

The measure of angle A is 55°.
Solution:
Let us take B be the adjacent angle of 145°.
<em>Sum of the adjacent angles in a straight line = 180°</em>
⇒ m∠B + 145° = 180°
Subtract 145° from both sides.
⇒ m∠B + 145° - 145° = 180° - 145°
⇒ m∠B = 35°
The adjacent angle of 145° is 35°.
In the image, angle B and angle A equal to 90°.
⇒ m∠B + m∠A = 90°
⇒ 35° + m∠A = 90°
Subtract 35° from both sides.
⇒ m∠A = 55°
The measure of angle A is 55°.
