Question

How do you do intercept slope

Answer 1

To find slope you need to use the coordinates of two points on the line. If the coordinates are (x1, y1) and (x2, y2) do  y2-y1 / x2-x1 to find the slope.

So far in the equation of a line, y=mx+b, you have the "m" which is the slope.

Plug in the slope, and the x and y values from one of the points and solve for b, which is the y intercept.

Here's an example if the coordinates are (1,4) and (2,6):

6-4/2-1 = 2/1 = 2

The slope is 2.

y = 2x + b

4 = 2(1) + b

4 = 2 + b

4-2 = 2-2 + b

2= b

The full equation is y = 2x + 2
