A line is perpendicular to y = = 3x - 9
and intersects the point (3,2).
What is the equation of this
perpendicular line?
y = [?]x + []
Hint: Use the Point-Slope Form: y - y1 = m(x – X1)
Then write the equation in slope-intercept form.

y = 1/3x + 1

Step-by-step explanation:

Point-Slope Form: y - y1 = m(x – x1)

y = 3x - 9 (3 is the slope)

*Perpendicular lines have reciprocal slopes. So 3/1 would be 1/3.

(3, 2)

y - y1 = m(x – x1)

y - 2 = 1/3(x - 3)

y - 2 = 1/3x - 1

 + 2           + 2

y = 1/3x + 1

Hope this helps!

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
