Linear line formula: y = mx + b
m = slope
b = y-intercept
In this case the question gives us what we need to substitute.
m = 4
b = 3
y = 4x + 3

Answer:

Step-by-step explanation:
Point-slope form of the equation of a straight line is:
(1)
The two points given in the problem are:

So, the slope of the line is given by:

And substituting into eq.(1), we find:

The intent of the construction appears to be to produce tangents from point P to the circle O. There are several possible next steps:
• Name the point of intersection just created between the arc and circle O
• Draw a line (or segment) between points P and J
• Draw a line (or segment) between point P and the intersecting point just created on circle O.
