Yes it can. A linear equation in the form of y=mx+b can always be graphed used the x and y intercepts.

What are the intercepts of 2x-3y-4z-24?
The question does not contain an equation but an expression. An equation can have intercepts, an expression cannot.
How do you graph y-4-3x plus 6?
With great difficulty because a straight line equation must contain an equality sign in order for it to be graphed onto the Cartesian plane.
How are functions equation slopes and graphs related?
There are some relationships but not all relationships are always true. Any function can be represented by an equation. But all equations are not functions. For example, y = sqrt(x) is the equation of the square root relationship which can be graphed as a parabola on its side, but it is not a function. It has slopes at each point. Some functions can be plotted as graphs but not all. A function such as f(x) = 1 when x is rational, and f(x) = 0 when x is irrational has no slope and cannot be plotted as a graph. A graph of a vertical line is not a function.
Is it true that some quadratic functions cannot be graphed?
All quadratic functions with real coefficients can be graphed on a standard x-y graph. Not all quadratic functions have real roots, maybe that's what you were thinking of?
Can you measure a line even though it goes on forever?
You cannot measure its length but you can measure its slope and intercepts.

What are the x and y intercepts of the equation 5-y-3x?
The question does not contain an equation (or inequality) but an expression. An expression cannot have intercepts.
What is the x intercept for yx-8?
yx - 8 is an expression, not an equation nor an inequality. Consequently it cannot be graphed and so cannot have an intercept.

With great difficulty because a straight line equation must contain an equality sign in order for it to be graphed onto the Cartesian plane.
How do you graph y2x?
y2x is an expression, which cannot be graphed because we don't know what it equals. y = 2x, y2 = x, and 2y (or y2) = x are all things that could actually be graphed.

What is the slope of the line with equation y -7x?
y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.

What is y equals 2xexponent2 plus 3x-1?
y=2x2 + 3x-1 To find the zeros of this equation (when y=0) set the equation = 0 0=2x2 + 3x-1 Now, you can either graph the equation in a graphing calculator and find the x intercepts (where the function crosses the x-axis and y=0) or you can factor the quadratic equation by "smiling" or reverse foiling. However, this equation cannot be easily factored. Therefore, using a graphing calculator will provide the correct answer of x= -1.780776 and x= 0.28077641 You can also use the quadratic formula where the general form of a quadratic equation is ax2 +bx+ c=0=y In order to use the quadratic formula, you simple plug the corresponding values into the x= equation. This will produce the same results as graphing and finding the x intercepts.
What is the equation for Standard Form?
Ax+By=C A- Cannot be negative Equation- Cannot have decimals or fractions in it
What is the slope for the equation 7?
Equation 7 is not an equation and so cannot have a slope.
