Slope equation maker3/26/2023 ![]() ![]() What is the y-line intercept of a linear function? This means whenever we go one square to the right, we have to go three squares down to be on the graph again. If we go one square to the right of any point on the graph, we have to go two squares up to be on the graph again.Īnother example, this time with negative slope: It says how may units you have to go up / down if you go one unit to the right. The slope of a linear function corresponds to the number in front of the x. The graph of a linear function is always a line.Ī similar word to linear function is linear correlation. Here is an example:ĭein Browser unterstützt den HTML-Canvas-Tag nicht. The general form of a linear function is, where m is the slope and b is the y-axis intercept. A negative slope moves downward from left to right and a line with positive slope moves in the upward direction from right to left.A linear function is a function whose graph is a line. ![]() The slope can be positive or negative, based on its direction. The direction of a line is described by its slope. If this value is negative for a line, then the line has a negative slope. The slope of a line is found by the ration of difference in y-coordinates to the difference in x-coordinates. An example for slope intercept form equation is y = 3x 5 What is a Line With a Negative Slope?Ī line for which the slope in negative is said to move from left to right in a graph. ![]() Here 'm' is the slope of the line and 'b' is the point at which the line intercepts the y - axis. The equation of a straight line which is of the form y = mx b, is called the slope intercept form. The formula to find the slope of a line is m = (y 2-y 1)/(x 2-x 1) What is Slope-Intercept Form? How to Find the Slope of a Line?įor two coordinates, (x 1,y 1) and (x 2, y 2), the slope of a line is the ratio of difference between the difference between the y coordinates and the difference between x coordinates, also known as the rise over the run. 'm' is referred to as the slope of the line, and 'b' refers to the 'y -intercept' of the line. ![]() It is called as the slope intercept form. Y = mx b is a representation of equation of a straight line. The slope intercept form of the line is y = - 2 x 2. Substituting the given values in the slope-intercept form equation we get, 4 = (-2) (-1) b. It is given that slope (m) = -2 and the coordinates through which the line is passing through is (-1,4). We know that the slope-intercept form of a line is y = mx b. Let us derive the formula to find the value of the slope if two points \((x_ b\)Īpplying, m =2 and b = 1 in the equation of the line(y = mx b), we get y = 2x 1 Thus the equation of the straight line is y = 2x 1Įxample 2: Find the slope-intercept form of a line with slope -2 and which passes through the point (-1.4). Thus the formula to find m = change in y/ change in x We know that the equation for the slope of a line in the slope-intercept form is y = mx b Let (x,y) be any other random point on the line whose coordinates are not known. Let us consider a line whose slope is 'm' and whose y-intercept is 'b'. Let's derive this formula using the equation for the slope of a line. Y = mx b is the formula used to find the equation of a straight line, when we know the slope(m) and the y-intercept (b) of the line. To determine m, we apply a formula based on the calculations. ![]()
