Final answer:
To find a point on the perpendicular line, calculate the slope of the original line and then use a known value of x to find the value of y on the perpendicular line.
Step-by-step explanation:
To find a point on the perpendicular line from the given equation that is not the y-intercept, we need to first find the slope of the given line which is the negative reciprocal of the slope of the original line. The given equation is y = 4x−2, so the slope is 4. The negative reciprocal of 4 is -1/4. So, the slope of the perpendicular line is -1/4.
Next, we need to find a point on the perpendicular line. Let's choose x = 8.
Substitute x = 8 into the equation y = -1/4x + b and solve for y. y = -1/4(8) + b = -2 + b.
So, when x = 8, y = -2 + b. The point on the perpendicular line for x = 8 is (8, -2 + b).
