Answer:
Step-by-step explanation:
The formula of a slope:
We have two points (-6, -8) and (-14, 4).
Substitute
Answer:
<em>the measure of the angle formed by given lines is 90°</em>
Step-by-step explanation:
<u><em>Line 1: </em></u>
2x - 7y + 6 = 0
- 7y = - 2x - 6
y = x +
<em>Slope of line 1:</em>
=
<u><em>Line 2: </em></u>
14x + 4y - 17 = 0 ⇔ y = - x +
<em>Slope of line 2: </em>
= -
= - × = - 1 ⇒ <em>lines are perpendicular</em>
1) 7y+14
2) 16a-32
3) 64b
