Linear function y=mx+b examples
Linear function y=mx+b examples- b tends to be the y intercept which can be worked out given that you have the gradient and any coordinate of a point on that line Just substitute them values in, rearrange to make b the subject which will give you the yintercept (b) For example y = 2x b and you know that the coordinate (5, 2) lies on this function Simple substitute them in and work out your value of b 2 = 2(5) b bLinear Equations and y = mx b Class Examples Write the slopeintercept form of the equation of each line (y = mx b) 1) Homework Write the slopeintercept form of the equation of each line y = mx b
Slope Intercept Form Of A Straight Line Y Mx B Chilimath
The coefficients in slopeintercept form Besides being neat and simplified, slopeintercept form's advantage is that it gives two main features of the line it represents The slope is The coordinate of the intercept is In other words, the line's intercept is at For example, the line has a slope of and a intercept atGet stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us!Every straight line can be represented by an equation y = mx b The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y The equation of any straight line, called a linear equation, can be written as y = m x b, where m is the slope of the line and b is the yintercept
Horizontal Lines The equation of a horizontal line is y = b where b is the yintercept Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx b becomes y = 0x b y = bAlso,since the line is horizontal, every point on that line has the exact same yAnswer (1 of 6) There are so many ways this can be used in real life I actually asked my math teach this when he was teaching it to us a while back I didn't realize how present it really is Have you ever been to an amusement or theme park?It is found by solving the equation 0= mx b Interactive Example Now explore how the values of the yintercept, b, affect the graph of the linear function y = mx b Algebraic Example Find the vertical and horizontal intercept of the linear function Solution Since f(0) = 72(0) 250 = 250, the vertical intercept is 250 This means
Applying, 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 1 Example 2 Find the slopeintercept form of a line with slope 2 and which passes through the point (14) Solution We know that the slopeintercept form of a line is y = mx bY b m = x y −b mx = y – b y = mx b Use the definition of slope ABpasses through (x, y) and (0, b), so that x2 = x, x1 = 0, y2 = y, and y1 = b Solve for y SlopeIntercept Form of a Linear Equation The slopeintercept form of the equation of a line is y = mx b, where m is the slope and b is the yintercept Let (x, y) and (x1, y1) beY = mx b, where m is the slope of the line and b is the yintercept How to graph an equation given in slopeintercept form?
