Answer 7

Step 1: First of all we require starting points say (x1, y1) and ending points (x2, y2) of line. Now calculate the Slope of line. We have a formula to get the slope of line:

m = (y2 - y1) / (x2 - x1),

Assume that we have the coordinates (2, 0) and (-1, 3) then slope of line will be:

m = (3 - 0) / (-1 - 2) = -1,

Step 2: Now we will calculate the y- intercept. We will multiply the slope of line with starting 'x' point and subtract it from the starting 'y' point as:

y intercept = 0 - (-1) * 2 = 2.

Step 3: Now as we know that equation of line is y = mx + c. Here 'm' is the slope of line and 'c' is the y- intercept of line. We have already calculated 'm' and 'c' of line. Now we will place these values in line equation.

Y = mx + c,

Y = -x + 2,

Step 4: If we want to verify the equation we can put the coordinates in equation and verify it.

0 = -2 + 2 = 0 and,

3 = 1 + 3 = 3.
