45 is the median of your question
Answer:
they are perpendicular
Step-by-step explanation:
because the slope are opposite which means the lines intersect.
Answer:
2
Step-by-step explanation:
Substitute a = - 6 into the expression, that is
a² + 7a + 8
= (- 6)² + 7(- 6) + 8 = 36 - 42 + 8 = - 6 + 8 = 2
A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4
The final equation is y= -4/3x + 21/4
The y intercept is (21/4).
.8 repeating. I believe is this answer.
