How do you write in terms of x?
The answer in terms of x would be 20–2(x^2). It means you don’t need to solve for x; you just answer the question in its simplest form.
How do you graph an equation with x?
The graph of x = a is a vertical line passing through the point (a, 0) on the x-axis. To graph a vertical line, such as 4x + 12 = 0, solve the equation for x to write it in the form x = a, plot the point (a, 0) on the x-axis, and draw a vertical line through it (see Example 5).
What does write an equation in terms of X mean?
Answer: When we explicitly express the dependant variable (Y) in relation to the independent variable (X), we call that as ‘Y is expressed in terms of X’. Let us understand more about algebraic expression and thereby find the answer to the given question.
What does solving in terms of X mean?
Solve for x means find the value of x that would make the equation you see true. Think about this equation: x + 1 = 3. If you were asked to solve it, that would mean finding some value for x that gives you three when you add one to it.
How do you find the equation of a graph from points?
Steps to find the equation of a line from two points:
- Find the slope using the slope formula.
- Use the slope and one of the points to solve for the y-intercept (b).
- Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
How do you graph the equation of a line?
To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value.
How do you make a graph from an equation?
Use the y=mx+b formula. To graph a linear equation, all you have to do it substitute in the variables in this formula. In the formula, you will be solving for (x,y). The variable m= slope. The slope is also noted as rise over run, or the number of points you travel up and over. In the formula, b= y-intercept.
How to plot a graph from an equation?
Make sure the linear equation is in the form y = mx+b.
Can we find the equation from a graph?
Finding the Equation of a Line from Its Graph Suppose you are given the graph of a line in the coordinate plane, and asked to find its equation. If you can find the y -intercept and the slope, you can write the equation in slope-intercept form (unless, of course, it’s a vertical line.)
How do you solve a simple equation?
To solve a simple linear equation, start by moving the numbers with a variable attached to one side of the equation and the numbers without a variable attached to the other side. To move a number to a different side, you need to subtract it from both sides.
