Hey can someone tell me the steps to solving a system of equations with graphing
1 answer:
Answer:
Let's go through the following example to show how to solve a system of equations by graphing. I won't solve this system, I will just show how to.

<h3>
If you can use an online graphing calculator...</h3>
If you have an online grapher (like Desmos) at your disposal, then you can put each equation in it as it is.
- Lines intersect -> Put your cursor over the point of intersection to get the solution.
- Lines never intersect -> The lines are parallel and there is no solution
- Lines perfectly fall on each other -> The lines are the same and have infinite solutions
<h3>
If you have a physical graphing calculator (like TI-84)</h3>
1. Get both equations in the form
by solving for y.

2. Put both equations in the graphing calculator
- Lines intersect -> Find the intersection point using your graphing calculator's mechanics (each one is a little different)
- Lines never intersect -> The lines are parallel and there is no solution
- Lines perfectly fall on each other -> The lines have the same equation and have infinite solutions
<h3>
If you just have graphing paper...</h3>
1. Get both equations into the form
by solving for y.

2. Plug in a few different points for x and calculate their y-values.
3. Plot those points on the graph paper
- Lines intersect -> Find the intersection point's coordinates to get the solution for x and y.
- Lines never intersect -> The lines are parallel and there is no solution
- Lines perfectly fall on each other -> The lines have the same equation and have infinite solutions.

Answer:
40.8
Step-by-step explanation:
48 * .15 = 7.2
48 - 7.2 = 40.8
-6.25 is the value of p. First distribute the 8 to the parentheses and then solve the equation
Answer: 9.3 because it’s a decimal .
Step-by-step explanation:
Answer:
should be a plane.
a plane is two dimensional and has intimate length and width. so it contains infinite lines.
Start by writing what is said:
2x + 4 = -6
From there just solve for x:
Subtract 4 from both sides
2x + 4 - 4 = -6 - 4
2x = -10
Divide by 2 to get x by itself
2x/2 = -10/2
x = -5
