Answer:
B; (2,-4)
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
So from the question, when we look at the given equation, its slope is -1/2
mathematically, when two lines are perpendicular, the product of their slopes is -1
thus;
m1 * m2 = -1
m2 * -1/2 = -1
-m2 = -2
m2 = 2
The general equation form is;
y-y1 = m(x-x1)
where (x1,y1) = (4,0)
y-0 = 2(x-4)
y = 2x - 8
So, now we look at the point that will work for this equation
For the line that will work, if we substitute its x-value, we get the y-value
Let us take a look at option B
y = 2(2) -8 = 4-8 = -4
we can see that (2,-4) works
Answer:
18
Step-by-step explanation:
18/24 is a 1/2 reduction from 36/48.
3/4 is simplest form.
D. It has a positive slope and negative y- intercept.
Step-by-step explanation:
2y -3x = -4
We can rewrite the equation in the form of y = mx+ b where m is the slope and b is the y - intercept as,
2y = 3x- 4
Dividing all the terms by 2, we will get,
2y/2 = 3x/2 - 4/2
y = (3/2)x -2
So the slope is 3/2 which is positive and y-intercept is -2 which is negative.
Answer:
2.3 2 1/3
Step-by-step explanation: you add up all the bikes then divide them by 3 because that's the number of people
Y=6x+1
y=6(5)+1
y=30+1
y=31
D. (5, 31)
hope this helps!
