1 Answer. No, every straight line is not a graph of a function. Nearly all linear equations are functions because they pass the vertical line test. The exceptions are relations that fail the vertical line test.
How do you determine a function on a graph?
Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.
How do you graph a line from an equation?
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 find the equation of a line that passes through two points and is parallel?
The equation of the line in the slope-intercept form is $$$y=2 x + 5$$$. The slope of the parallel line is the same: $$$m=2$$$. So, the equation of the parallel line is $$$y=2 x+a$$$.
Is a vertical line a function?
The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.
Is a graph with two lines a function?
A linear function is a function whose graph is a straight line. The line can’t be vertical, since then we wouldn’t have a function, but any other sort of straight line is fine. This graph shows two lines, rather than one straight line.
