1. slope = 2; y-intercept = -1 2. slope = 53 ; y-intercept = 4 3. slope = -3; y-intercept = 2 4. slope = -1; y-intercept = 7 5. slope = 14 ; y-intercept = 0 6. slope = 52 ; y-intercept = -3

Step-by-step explanation:

1. slope = 2; y-intercept = -1

y = 2x-1

2. slope = 53 ; y-intercept = 4

y = 53x + 4

3. slope = -3; y-intercept = 2

y = -3x + 2

4. slope = -1; y-intercept = 7

y = -1x + 7

5. slope = 14 ; y-intercept = 0

y = 14x

6. slope = 52 ; y-intercept = -3

y = 52x + 3

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

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
