I dont have any additional details.
First, we want to calculate the slope.
m=(9-2)/(4-3) = 7
We know the form of a line in slope-intercept form is y=mx+b, and we have found m to be 7.
Let us use the point (3,2) to find b.
2=7(3)+b, or 2=21+b
Solving for b, we get b=-19.
Therefore, the equation of the line in slope-intercept form is y=7x-19.
