Solution
Solution Steps
Step 1: Find the slope of the perpendicular line
To find a line perpendicular to the given line y=0.3333333333333333x+1, we use the negative reciprocal of m.
The slope of the perpendicular line, m′, is −0.3331 = -3.
Step 2: Use the point-slope form to find the equation of the perpendicular line
Using the point (−1,3) and the slope m′=−3, we apply the point-slope form:
y−3=−3(x+1)
Simplifying to the slope-intercept form y=mx+b, we solve for y:
y=−3.0x+0
Final Answer:
The equation of the line perpendicular to y=0.3333333333333333x+1 passing through (−1,3) is y=−3.0x+0.
