Equation of the perpendicular
y= 2x+6
slope of the perpendicular = 2
slope of the req. line = -1/2
equation of the req. line
y - y1 = m(x - x1)
y - 2 = -1/2(x + 4)
2(y - 2) = -1(x + 4)
2y - 4 = -x - 4
2y = -x
y = (-1/2)x
this is your req. equation of line.
I guess by slope, you mean gradient.
By knowing the gradient, and a coordinate at which the line passes through, we can use:
y - y1 = m(x - x1)
to get the equation of the line in the form (y = mx + c).
y - 5 = (-3 / 4)(x - 4)
y - 5 = (-3 / 4)x + 3
Rearrange.
y = (-3 / 4)x + 8
I would round them so it would be 500 divided by 20
The answer should be close to 25
Answer: -3000
Step-by-step explanation:
That answer was on quizlet
Answer:
yes it is a 75% decrease
Step-by-step explanation:
since 80-20=60
60/80=6/8=3/4
3/4=75%
