Remember slope is

. In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is
Angle 4 is the same as angle 6, 75 degrees, there are alternate interior angles.
Answer:
the slope is 3
Step-by-step explanation:
its rise over run it goes up three and moves to the right one so 3/1=3
slope = change in y / change is x
slope = rise / run
change in y = -1 (goes down 1)
change is x = 4 (goes right 4)
slope = -1/4
y-intercept, when x = 0
y-intercept = 1 = (0,1)
Answer:
Step-by-step explanation:
(9 + m)(-m + 9) = (9 + m)(9 - m) {(a+b)(a-b) = a² - b²}
= 9² - m²
= 81 - m²
= -m² + 81
