If you multiply the slopes of two perpendicular lines, the product is -1.
(As long as neither line is vertical.)

The slope of line g is - 1/2.

= -1/2 • _= - 1
So, the slope of line h is ___
The equation for line h is
y = ___x + _ .

Slope of the line h is 2.

The equation for line h is y = 2x + 4.

Solution:

General equation of a line is y = mx + c,

where m is the slope of the line and c is the y-intercept.

In the given image, line g and line h are intersecting lines and perpendicular to each other.

Equation of line g is .

Slope of the line g () =

If two lines are perpendicular, then the product of the slopes is –1.

⇒

To find the slope of the line h:

Slope of the line h is 2.

To find the equation of a line h:

Line h passing through the point (0, 4) and slope 2.

Point-slope formula:

The equation for line h is y = 2x + 4.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
