Question

The equation of line CD is y = 3x - 3. Write an equation of a line perpendicular to line CD in slope-intercept form that contains point (3,1). Oy = 3x + 0 Oy = 3x - 8 Oy -x+ 2 Oy= y = x + 0​

Answer 1

• y = -1/3x + 2

Explanation:

Given line

• y = 3x - 3

Perpendicular lines have negative-reciprocal slopes, so the line will be:

• y = -1/3x + b

Use the point (3, 1) to find b:

• 1 = -1/3(3) + b
• 1 = -1 + b
• b = 2

The line is:

• y = -1/3x + 2
