Question:

On a coordinate plane, a line goes through (negative 3, 2) and (0, 1). A point is at (3, 4). What is the equation of the line that is perpendicular to the given line and passes through the point (3, 4)? y = –One-thirdx + 5 y = –One-thirdx + 3 y = 3x + 2 y = 3x − 5

Answer:

Option D:
y=3x-5 is the equation of the line

Step-by-step explanation:

It is given that the line passes through the points
(-3,2) and
(0,1)

We shall find the equation of the line that passes through the points
(-3,2) and
(0,1)

Slope
m=(1-2)/(0+3)


m=(-1)/(3)

Also, it is given that the line is perpendicular to the line having slope
m=(-1)/(3)

Since, we know that if two lines are perpendicular, then the product of the two slope is equal to -1.

Thus, we have,


m_1\cdot m_2=-1


(-1)/(3) \cdot m_2=-1


m_2=3

Thus, the slope of the line is
m=3 and passes through the point
(3,4)

Now, we shall find the equation of the line using the formula,


y-y_1=m(x-x_1)

Thus, we have,


y-4=3(x-3)


y-4=3x-9


y=3x-5

Thus, the equation of the line is
y=3x-5

Hence, Option D is the correct answer.
