What is the equation of a line in slope intercept form that is perpendicular to y=2/3x+2 and passes through the points (-2,2)? H
JulijaS [17]

Answer:

y = -\frac{3}{2}x -1

Step-by-step explanation:

Given

Perpendicular to y = \frac{2}{3}x + 2

Pass through (-2,2)

Required

Determine the line equation

First, we need to determine the slope of y = \frac{2}{3}x + 2

An equation is of the form:

y = mx + b

Where

m = slope

In this case:

m = \frac{2}{3}

Next, we determine the slope of the second line.

Since both lines are perpendicular, the second line has a slope of:

m_1 = \frac{-1}{m}

m_1 = \frac{-1}{2/3}

m_1 = -\frac{3}{2}

Since this line passes through (-2,2); The equation is calculated as thus:

y - y_1 = m_1(x - x_1)

Where

(x_1,y_1) = (-2,2)

This gives:

y - 2 = -\frac{3}{2}(x - (-2))

y - 2 = -\frac{3}{2}(x +2)

y - 2 = -\frac{3}{2}x -3

Add 2 to both sides

y - 2+2 = -\frac{3}{2}x -3 + 2

y = -\frac{3}{2}x -1
