Find the equation of the line joining the points (4, 9) and (-1, 0)
Fed [463]

The equation of the line joining the points (4, 9) and (-1, 0) is y = 9/5 x + 9/5

<h3>How to find the equation of a line?</h3>

The formula for calculating the equation of a line is expressed as:

y = mx + b

m is the slope

b is the intercept

Determine the slope:

Slope = 0-9/-1-4
Slope = -9/-5
Slope = 9/5

Determine the y-intecept

0 = 9/5(-1) + b

b = 9/5
Hence the equation of the line is y = 9/5 x + 9/5
