How do you graph y equals x squared minus 4?
its a simple parobola symmetric about y axis, having its vertex at (0,-4). we can make its graph by changing its equation in standard form so that we can get its different standard points like vertex, focus, etc.
Is a graph of an equation the same as an inequality?
no the graph will be written in slope intercept form or y=mx+b
Standard form of an equation?
ax+by=c
Which equation below represents a generic equation suggested by a graph showing a hyperbola?
A hyperbola is another form of a conical section graph like a parabola or ellipse. Its general form is x^2/a - y^2/b = 1.
What is the standard form of a linear equation?
Ax + By = C
What is the standard form for a quadratic equation?
Normally a quadratic equation will graph out into a parabola. The standard form is f(x)=a(x-h)2+k
What determines whether the graph of the quadratic function will open upward or downward?
The slope of your quadratic equation in general form or standard form.
What is y equals 8-2x?

Can a linear equation be graphed with only the slope and intercept when it is in standard form?
That's all you need to know in order to draw the graph. Note that it doesn't matter what form the equation is written in. The form of presentation doesn't change the slope or intercept.
What is standard form linear equation's?
A standard form of a linear equation would be: ax + by = c
Why is slope form important?
Slope form gives you a clear image of the graph automatically as soon as you see the equation. In any given equation y=mx+b, m is the slope, which helps you visualize how steep the graph is and in which direction it goes (increases or decreases). b is the y-intercept, which is just a fancy term for where the graph intersects the y-axis. Using slope form helps you graph the graph way easier than using another form, such as standard form (Ax+By=C. What a mess!).
How do you get the y intercept without having to draw a graph?
You can put the equation into slope-intercept form and the answer is right there, or you can put it in standard form and make the x coefficient and x "disappear" and solve the equation by dividing the number with y by the number on the other side of the equation.
What different information do you get from vertex form and quadratic equation in standard form?
The graph of a quadratic function is always a parabola. If you put the equation (or function) into vertex form, you can read off the coordinates of the vertex, and you know the shape and orientation (up/down) of the parabola.
What is 5y-90x equals 80?
It's a non-standard form of the equation for a straight-line graph with a slope of 18 and a y-intercept of 16.
Any equation whose graph is a line is a?
Such an equation can be written in several standard forms; here are two of them: Ax + By + C = 0 y = mx + b (that's the "slope-intercept form")
What is the formula for the standard equation of a line?
The standard expression for a straight line graph is y = ax + b
What is the standard form of an equation?
The standard form of an equation is Ax + By = C. In this type of equation, x and y are variables while A, B, and C are integers.
