See photo for solution and mark me as brainliest if i helped :)
A: although it seems like they are forming a 90º angle, they actually add up to a 89 º angle and therefore are not complementary
B: see photo
Answer:
-9/1
Step-by-step explanation:
A line that passes through (5, 1) can have ANY slope and ANY y-intercept. There are an infinite number of different lines that pass through that point.
The standard form: Ax + By = C.
The point-slope form:
7. We have the points (4, -7) and (2, -3). Substitute:
8. We have the points (1, 5) and (-10, -6). Substitute:
Answer:
A, undefined
Step-by-step explanation:
The general rule is that vertical lines are undefined slope, because there's literally no change in x values. The vertical line test also fails, meaning there is no slope. Horizontal lines have a slope of 0, while vertical lines don't own any numbers that are important except for x-axis numbers.
If you do y2-y1 over x2-x1, you literally get 1/0 which is nothing. 0/1 = 0, but 1/0 is nothing.
Hope this helps!
