Figure out math question

Math can be confusing, but there are ways to clarify questions and get the answers you need.

If there are two points (x 1, y 1) and (x 2, y 2) connected by a secant line on a curve y = f (x) then the slope is equal to the ratio of differences between the y-coordinates to that of

m = y2 −y1 x2 −x1 m = y 2 - y 1 x 2 - x 1 Substitute in the values of x x and y y into the equation to find the slope. m = 6− (2) 9−(−7) m = 6 - ( 2) 9 - ( - 7) Simplify. Tap for more steps m = 1 4 m =

Figure out mathematic equation

The answer to the equation is 4.

Formula to find the slope of the line passing through two points is m = (y2 - y1)/ (x2 - x1) Substitute (x1, y1) = (1, 2) and (x2, y2) = (-4, 5). m = (5 - 2)/ (-4 - 1) = 3/ (-5) = -3/5 So, the slope of the given line is -3/5. Kindly mail your feedback to

Divide Δy by Δx to find slope m = Δy/Δx Example: Find the Slope Say you know two points on a line and their coordinates are (2, 5) and (9, 19). Find slope by finding the difference in the y
