2nd Option: x + y = -1

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I/Geometry

Step-by-step explanation:

Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.

Pluging in and chugging Point A into each equation should tell us what the equation should be.

Option 1

x - y = 1

-3 - 2 = 1

-5 ≠ 1

We see here that -5 does not equal to 1. Therefore option 1 is incorrect.

Option 2

x + y = -1

-3 + 2 = -1

-1 = -1

We see here that -1 does equal to -1. Therefore option 2 is correct.

Option 3

x + y = 1

-3 + 2 = 1

-1 ≠ 1

We see here that -1 does not equal to 1. Therefore option 3 is incorrect.

Option 4

x - y = -1

-3 - 2 = -1

-5 ≠ -1

We see here that -5 does not equal to 1. Therefore option 4 is incorrect.

We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
