Some algebra will show us why. Since the line has slope 2 and y-intercept 5, we can write its equation as y = 2x + 5. The equation of the circle is x 2 + y 2 = 25, so to find the points of ...

Find the slope of a line in Excel. Getty. In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format.

To find the equation of a line from two points, follow these steps: Find the gradient by calculating change in 𝑦-coordinates ÷ change in 𝑥-coordinates .

The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...
