Question

Write the equation of a line perpendicular to the line y = 2x - 3 that goes through point (4, 3)

Answer 1

Answer:

y = -1/2x + 5

Step-by-step explanation:

To get the perpendicular line first, take the negative reciprocal of the slope.

2 -> -1/2

So far, the equation is y - -1/2x ± b. (since we are using mx + b)

Since you want the point (4, 3) to cross over the line, we substitute values in.

3 = -1/2(4) + b

3 = -2 + b

b = 5

Your equation that fits the answer is -1/2x + 5.

Your welcome!
