Convert to slope intercept form 4x+5y=-20

y = (-4/5)x - 4

slope = m = -4/5

y-intercept = -4

Step-by-step explanation:

slope-intercept form: y = mx + b

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Isolate the variable, y.

First, subtract 4x from both sides:

4x (-4x) + 5y = -20 (-4x)

5y = -20 - 4x

Next, divide 5 from both sides to isolate the y:

(5y)/5 = (-20 - 4x)/5

y = (-4x - 20)/5

y = (-4/5)x - 4

y = (-4/5)x - 4 is your answer.

i dont know i just need points

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
