The expression can be solved by expanding the bracket and multiplying out the terms
Therefore, the expression can be simplified as;
Alternatively, using the theorem of difference of two squares, which is
Hence,
Y = mx + b, where m = slope = rise/run and b, the y intercept value
m = 1/1 = 1, then y = x + b.
We notice that y intercept is = - 1
And the equation is:
y = x - 1
The image is not clear you have to retake the picture I can’t see the numbers in the table
Every piece of cord is 1/10 of a meter long
Answer:
-5/2
Step-by-step explanation:
Slope = change in y over change in x or (y2-y1)/(x2-x1)
slope = (-13-(-3))/(6-2) = -10/4 = -5/2
