I assume you want it in slop-intercept form.
y = 3/4x + y-intercept (the graph isn't labeled)
If you just want to find the slope of the graph, it would be 3/4
A, B, C, and D have the coordinates (-8,1), (-2,4), (-3, -1), and (-6,5) respectively. which sentence about the points is true?
Trava [24]
Answer:
Option B is correct.
Step-by-step explanation:
To check if the lines are parallel or perpendicular, we need to find the slope of lines AB and CD
A=(-8,1), B= (-2,4), C= (-3, -1), and D= (-6,5)
Slope of AB = y₂-y₁/x₂-x₁
Slope of AB = 4-1/-2-(-8)
Slope of AB = 3/-2+8
Slope of AB = 3/6
Slope of AB = 1/2
Slope of CD = y₂-y₁/x₂-x₁
Slope of CD = 5+1/-6-(-3)
Slope of CD = 6/-6+3
Slope of CD = 6/-3
Slope of CD = -2
Lines are parallel if Slope of AB = Slope of CD
Lines are perpendicular if Slope of Ab = -1/Slope of CD
So, Slope of AB = 1/2
Slope of CD = -2
So, LINE AB AND LINE CD ARE PERPENDICULAR
Option B is correct.
It would take <u>35 minutes</u> to drive 1 km at a speed of 1.71 km/h.
<h3>How do distance and speed compare?</h3>
Speed is the ratio of distance traveled in a given time. Speed is given by distance/time.
The time can be computed by dividing distance by speed.
This implies that time is the quotient of distance and speed.
The total distance drove = 1 km
The driving speed = 1.71 km/h
Time = Distance/Speed
= 1/1.71
= 0.58 hours
= 0.58 x 60 seconds
= 35 minutes 5 seconds
Thus, to travel 1 kilometer at the speed of 1/71 kilometers per hour would take <u>35 minutes</u>.

Put parentheses around the '6 + 12 ÷ 6' and another parentheses around the '6 + 12':-
8 x 5 - ((6 + 12) ÷ 6)
= 40 - (18 ÷ 6)
= 40 - 3
= 37
