Ineed an ! match the answers with the boxes down below a. y = 2x + 1 b. y = −0.5x + 1 c. y = −2x − 1 d. y = −2x + 1 e. y = 0.5x + 1 f. y = 2x − 1

x-intercept is the point where a line crosses the x-axis.

y-intercept is the point where a line crosses the y-axis.

(A)

Set y =0 to solve for x;

2x+1=0

⇒

x- intercept of the line is; (, 0)

Set x= 0 to solve for y;

y=0+1=1

then, y-intercept is, (0,1).

(B)

y = -0.5x+1

Same process for B as we have done in (A);

x-intercept = (2,0)

y-intercept = (0,1)

(C)

y= -2x-1

x-intercept = (, 0)

y-intercept = (0,-1)

(D)

y= -2x+1

x-intercept =  (, 0)

y-intercept = (0,1)

(E)

y =0.5x+1

x-intercept = (-2,0)

y-intercept = (0,1)

(F)

y = 2x-1

x-intercept = (, 0)

y-intercept = (0,-1).

So the answer for this is shown in the attachment below;

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
