I need help finding point slope form

1 Answer

We were given two points to find the equation of the line, these are (4,3) and (5,5).

We need to find the point-slope form, which can be writen as follow:


y-y_1=m\cdot(x-x_1)_{}

Where (y1,x1) is one point on the line and "m" is the slope of the line. We first need to find the slope:


m=(y_2-y_1)/(x_2-x_1)

Where (y1,x1) and (x2,y2) are the two known points. We can find the slope by applying the two points given to us:


m=(5-3)/(5-4)=2

We can know write the expression of the line:


y-5=2\cdot(x-5)
