# Does y 3x 5 represent a line?

## Does y 3x 5 represent a line?

The equation y=−3x+5 is in slope intercept form, and represents a straight line in which -3 is the slope, and 5 is the y -intercept.

## What is the slope of the graph of y 3x 5?

Using the slope-intercept form, the slope is 3 .

What is a line perpendicular to y 3x 5?

y = 3x + 5 is a line with a slope of m = 3. A line perpendicular to that line will have a slope that is the negative reciprocal of 3. The reciprocal of 3 is 1/3. So the negative reciprocal of 3 is -1/3.

Is Y 3x − 5 a function?

Since this is a linear function, its graph is a straight line stretching from – infinity to infinity on both x and y axes, hence domain and range is all real numbers from – infinity to infinity.

### What does Y 3x mean?

y=3x
y=3x. This equation is in slope intercept form, and can be rewritten as: y=3x+0 , where 3 is the slope and “0” is the y-intercept. Determine a few points on the line by choosing values for x and solve for y . Points.

### How many solutions y 3x 5 has?

the equation y=3x+5 has infinite solutions.

Does Y =- 3x 5 have a positive slope?

y=−3x+5 is in the slope-intercept form for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. Therefore, the slope, m , from the given equation is −3 .

Is y 3x 5 parallel or perpendicular?

y = 3x + 5 and y = 5x + 3 both have positive slopes (m = 3 and m = 5, respectively), so they aren’t perpendicular. y = 3x/5 – 3 and y = 5x/3 + 3 both have positive slopes, so again they aren’t perpendicular.

## What is the slope of Y 5?

The equation in slope intercept form, would read, y = 0x + 5. The reason the x term drops out of the equation is because any variable multiplied by 0 is going to be zero, and drops out of the equation. Thus it is simply read y= 5. Since the slope is equal to zero, this graph would be seen as a horizontal line.

What is the formula for graphing?

Graphing Linear Equations Use the y=mx+b formula. To graph a linear equation, all you have to do it substitute in the variables in this formula. Draw your graph. Graphing a linear equation is the most simple, as you don’t have to calculate any numbers prior to graphing. Find the y-intercept (b) on your graph.

How do you graph a linear function?

Steps Make sure the linear equation is in the form y = mx + b. This is called the y-intercept form, and it’s probably the easiest form to use to graph linear equations. Plot the b number on the Y-axis. Your b is always going to be a rational number. Convert m into a fraction.

### How do you calculate the slope of a linear equation?

Slope can also be calculated using the slope formula, when you have two points on the line: b= the y-intercept. This is the point in which the line intercepts the y-axis. A linear equation is an equation that describes a straight line. One form of a linear equation is the slope intercept form which is written, y=mx +b.
