Point slope form of a line is the standard equation:
yy1=m(xx1)
where x1 and y1 are a point the line intersects and m in the slope, so your line:
y5=2(x2) is your line.
you can convert it to slope intercept form:
y=2x+9
so the slope m=2 and the y-intercept is 9

We must assume that the line is a straight line.
The equation of a straight line in slope/point form is:
(yy1)=m(xx1)
Where the line has a slope m and passes through the point (x1,y1)
Here we have a line of slope -2 passing through the point (2,5)
(y5)=2(x2)
y=2x+4+5
y=2x+9
is the equation of the line in slope/intercept form.
