WebIn high-school mathematics, the equation for a straight line is usually written in the order … height = 5.76 * age + 85.68. or in general form, as y =m*x + c where m is the number for the gradient or slope of the line, and c is the intercept, the y-value when x=0. WebGiven that the trendline is straight, find the slope by choosing any two points and calculating: (A) slope = (y1-y2)/(x1-x2) Then you need to find the offset for the line. The line is specified by the equation: (B) y = offset + slope*x. So you need to solve for offset. Pick any point on the line, and solve for offset: (C) offset = y - (slope*x)
WebThe Trend Analysis Formula can be calculated by using the following steps: Step 1: Firstly, decide the base year and then note down the subject line item’s value in the base year. Step 2: Next, note down the value of the line item in the current year. Step 3: Now, the formula for trend analysis in terms of change in amount can be derived by ... WebStep 2: Find the y y -intercept. We can see that the line passes through (0,40) (0,40), so the y y -intercept is 40 40. Step 3: Write the equation in y=mx+b y = mx +b form. The equation is y=-0.5x+40 y = −0.5x +40. …
