Find the equation of the line through point (3,4) and perpendicular to y=−2x−4. Use a forward slash (i. e. "/") for fractions (e. g. 1/2 for 12). Y=

y = 1/2x + 5/2

Step-by-step explanation:

Remember that if a line is perpendicular to another line, they intersect, and create a 90 degree angle. Because of this, we know that their slopes cannot be the same. In fact, to find a perpendicular line, you must find the Negative Reciprocal of the given line's slope.

A negative reciprocal of -2, would be positive 1/2.

So, this is the slope of the line perpendicular to y = 2x-4.

You're given a point that this line passes through, however you need the Y-Intercept. Thus, you must plug in the point to the slope formula.

You should have: 4 = 1/2(3) + b

Now we solve for b.

4 = 3/2 + b

Subtract 3/2 from both sides

5/2 = b

Now that we have our y-intercept we can finish writing the equation for the line perpendicular by simply taking out the points we plugged in. Leave the slope however.

Y = 1/2x + 5/2

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
