WebA graph passes the horizontal test if every horizontal line crosses, or intersects it, at one or fewer points. If the graph passes the test, it is a one-to-one function – every specific input corresponds to exactly one output. Functions can also be many-to-one, but many-to-many and one-to-many relations are technically not actually functions. WebA line graph is a type of chart or graph that is used to show information that changes over time. In other words, a line graph is a chart that helps us to visualise the value of something over time. A line graph has two axis – a horizontal axis which is known as the x – axis and a vertical axis which is known as the y – axis.

WebInteractive Algebra. Included in this worksheet are 25 problems over horizontal and vertical lines. It is separated into 4 parts: Part 1: Given the equation, identify the slope and graph the line. Part 2: Given the graph, identify the slope and write the equation. Part 3: Given the verbal description, graph the line. WebHow do you find the equation of a line? To find the equation of a line y=mx-b, calculate the slope of the line using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. Substitute the value of the slope m to find b (y-intercept). marine sales turnover policy ppt
