You can tell that a line is parallel if the lines can go on forever without crossing or intersecting. A line is perpendicular when the lines intersect at a right angle. If the slopes are either equal or negative reciprocals, they cannot be parallel or perpendicular.

Answer:
- Francesca: 2879 1/6 miles
- Sophia: 575 5/6 miles
Step-by-step explanation:
For each mile that Sophia ran, Francesca ran 5 miles. Then Sophia ran 1/6 of their total. Sophia ran ...
(1/6)(3455) = 575 5/6 miles
Francesca ran the remaining miles:
3455 -575 5/6 = 2879 1/6 miles
Answer:
70
Step-by-step explanation:
Because PQ tangent to circle, angle P is 90
angle S = 180 - 90 - 20 = 70
Equation in slope-intercept form of the line that passes through (6,-2) and (12,1) is:

Step-by-step explanation:
Given points are:
(x1,y1) = (6,-2)
(x2,y2) = (12,1)
The slope intercept form is:

We have to find the slope first

Putting the value of slope

To find the value of b, putting (12,1) in the equation

Putting the values of m and b

Hence,
Equation in slope-intercept form of the line that passes through (6,-2) and (12,1) is:
