A line is perpendicular to y =-1/3x +7
and intersects the point (4,2).
What is the equation of this
perpendicular line?

The equation of the perpendicular line is y = 3x – 10.

Solution:

Equation of the line:

Slope of this line,

If two lines are perpendicular, then the product of their slopes equal to –1.

The line passes through the point (4, 2).

Here,

Point-slope formula:

Add 2 on both sides of the equation.

y = 3x – 10

The equation of the perpendicular line is y = 3x – 10.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

answer: 2530

hope this
