How do I graph y+x= -3

Mathematics
1 answer:
Nitella [24]3 years ago
7 0

Answer:

Use Desmos.com/calculator

Step-by-step explanation:

Remember, y=mx+b

y is equal to any given y point

x is equal to any given x point

m is equal to slope

b is equal to the y-intercept, or where x = 0 and the line crosses the horizon line.

In order to graph the line correctly, you have to isolate y.

y+x=-3

y=-x-3 would be equal to y=mx+b format

slope is negative 1

y intercept is negative 3

start on the y line, go to (0,-3) and start your line.

slope is negative 1, so you go down one and right one.

1. The Cajun Heartland State Fair charges $1.25 per ticket for the rides. Johnny bought 25 tickets for the rides and spent a tot
vladimir1956 [14]

<u>Part (a)</u>

The variable y is the dependent variable and the variable x is the independent variable.

<u>Part (b)</u>

The cost of one ticket is $1.25. Therefore, the cost of 25 tickets will be: .

Now, we know that Johnny spent his money only on ride tickets and fair admission and that he spent a total of $43.75.

Therefore, the price of the fair admission is: $43.75-$31.25=$12.5

If we use y to represent the total cost and x to represent the number of ride tickets, the linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission can be  written as:

y=1.25x+12.5......Equation 1

<u>Part (c)</u>

The above equation is logical because, in general, the total cost of the rides will depend upon the number of ride tickets bought and that will be 1.25x. Now, even if one does not take any rides, that is when x=0, they still will have to pay for the fair admission, and thus their total cost, y=$12.5.

Likewise, any "additional" cost will depend upon the number of ride tickets bought as already suggested. Thus, the total cost will be the sum of the total ride ticket cost and the fixed fair admission cost. Thus, the above Equation 1 is the correct representative linear equation of the question given.

What is the equation of a line that passes through the point(3,-8)and has a slope of 0?
hram777 [196]

Answer: y=-8

Step-by-step explanation:

If the slope is zero that means that the line does not go up (or have any rise) and therefore must be a horizontal line. Since it passes through the point (3,-8), the equation has to be y=-8.
