You need to determine another point along the line or determine the slope of the line given the graph.
First, count the "rise" and "run" units along the graphs. To count the "rise" units, count the number of units it takes for the line to rise up. To count the "run" units, count the number of units it takes for the line to run left/right.
Remember:
- If you are running up along the line, then you are counting positive units for the "rise".
- If you are running left/right along the line, then you are counting negative/positive units for the "run".
Use this simplified form:
m = slope form = rise / run
Then, use the point-slope form to determine the equation of a line.
y - y0 = m(x - x0)

Find the point slope equations of the line using the point 7 4 and slope of?
y-4=3/2(x-7)
What is the shortest path between a line and a point not on that line?
The shortest path is a line perpendicular to the given line that passes through the given point.
How do you find a line that goes through a given point?
You need either a point and the slope of the line or two points. Then you use the point slope form of the line or the slope intercept form to write the lines.A given point has an infinite number of lines going through it, that is why you need more information.
How to measure the point at which two tangents intersect each other?
To measure the point at which two tangents intersect each other, find an equation for each tangent line and compute the intersection. The tangent is the slope of a curve at a point. Knowing that slope and the coordinates of that point, you can determine the equation of the tangent line using one of the forms of a line such as point-slope, point-point, point-intercept, etc. Do the same for the other tangent. Solve the two equations as a system of two equations in two unknowns and you will have the point of intersection.
How to Derive the formula of distance between a point and a line?
You must first write an equation for the line through the point perpendicular to the line. Then, find the intersection between the two lines. Lastly, use this point and the distance formula to find the length of the perpendicular segment connecting the given point and the original line. That will lead to the following formula, d = |AX1+BY1- C|/(sqrt(A2+B2)), Where A, B and C represent the coefficients of the given line in standard form and (X1,Y1) is the given point.
