Answer:
Step-by-step explanation:
an equation is : Use the point-slope formula.
y - y_1 = m(x - x_1) ; m : the slope when : x_1 = -3 and y_1 = 7
- 2 ×m = - 1 because this line is perpendicular to the line y= -2x-5 when the slope is -2
so : m= 1/2
an equation is : y - 7 =(1/2)(x+3)
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Answer:
Disagree 15 minutes
Step-by-step explanation:
Answer:
x=4 y=0
Step-by-step explanation:
You add the two equations together to get 3x=12. You derive x=4 and y=0 from that.
Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.
