How do you write an equation of the line that passes through (-3,4) and (1,0)?
The line equation is of the form
As the line passes through this two points
they both obey the equation
So, the equation of the line that passes through those points is
First step: find the slope (gradient) of the line:
It doesn't matter which of the two given points we decided is 'Point 1'
Similarly for the other point,
Now that we know the slope, we can use it and the value of one of the points we were given to find the y-intercept of the line. This is the point where the line crosses the y-axis. The y-axis is the line
