You can easily calculate this and any other expression of this kind using this principle
Now you multiply the numerator of the first fraction (36) with the denominator of the second fraction (4) and the denominator of the first one (1) with the numerator of the second one (3). You get:
To find out which option is correct, we can write the equation in point-slope form ourselves.
Use the point-slope formula to write the equation in point-slope form. Substitute the , , and for real values.
Since represents the slope, substitute in its place. Since and represent the x and y values of a point the line intersects, substitute the x and y values of (5,1) into the formula as well. Substitute 5 for and 1 for . This gives the following equation:
