What is the standard form of a line with the x intercept of 4 and y intercept of -2?

Mathematics
1 answer:
earnstyle [38]3 years ago
3 0

Answer:

x-2y=4

Step-by-step explanation:

So from the question we know the following:

When something is x intercept it means y=0 so we have (4,0)

When something is y intercept it means x=0 so we have (0,-2)

Now you use these to find the slope using the formula m= (y2-y1)/(x2-x1)

Plug in the values

m= (-2-0)/0-4)

m=(-2/-4)

m= 1/2

x-2y=4

Now you just plug this in slope intercept form y=mx+c, where c is y intercept

y=1/2 x -2

Standard form: ax+by=c

y=1/2 x -2 (rearrange to match the above equation)

-1/2 x +y =-2 (multiply both sides by 2 because we can't have a fraction for a in the standard form)

-1x+2y=-4 (now multiply both sides by -1 because a cannot be negative)

x-2y=4

What is the endpoint formula given midpoint?
zysi [14]

Answer:

  B = 2M -A

Step-by-step explanation:

For given endpoint A and midpoint M, the other endpoint B can be found using the definition of the midpoint:

  M = (A+B)/2

  2M = A+B . . . . . multiply by 2

  2M-A = B . . . . . subtract A

The second endpoint can be found by subtracting the given endpoint from twice the midpoint:

  B = 2M -A

If you roll two number cubes what is the probability of rolling two sixes
vazorg [7]

Answer:

the probability of rolling two 6's is 2 out of 12 or 0.167 rounded to the nearest thousandth

Step-by-step explanation:

there are 6 sides on a cube so that's 5 other chances that you'll get 1-5 and having two cubes doubles the chance.

egoroff_w [7]

Answer:

The last graph best represents the story

Step-by-step explanation:

Mary left for school from rest. So the initial speed is zero.

So we start from the origin and draw a straight line with a positive slope to running, that is as time increases , distance covered also increases.

When she is resting, her speed is zero so we draw a horizontal line to indicate this second phase of her journey.

After resting she still continued her journey to school.

This part also has a positive slope.

A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the
Alexus [3.1K]

4x+6y=56 and y=4x can be used to determine the number of small cars rented and the number of large cars rented, where x represents number of small cars and y represents number of large cars.

Step-by-step explanation:

Number of people hold by small cars = 4

Number of people hold by large cars = 6

Let,

Number of small cars = x

Number of large cars = y

The students rented 4 times as many large cars as small cars,

y = 4x    Eqn 1

which altogether can hold 56 people.

4x+6y=56   Eqn 2

4x+6y=56 and y=4x can be used to determine the number of small cars rented and the number of large cars rented, where x represents number of small cars and y represents number of large cars.
