Gradient = rise/run = -1/2
Thus:
y = -1/2x + c
Solve for c:
Pick a point for the values of y and x
(2,-2)
-2 = -1/2 (2) + c
c = -2 + 2
c = 0
Thus the equation is
y = -1/2x
14-7=7
The greates minus the least number answer is 7
For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function
First we need to define what a like term is:
Like term meaning:
Terms whose variables (such as x or y) with any exponents (such as the 2 in x2) are the same. Examples: 7x and 2x are like terms because they are both "x".
Answer (for question 1):
For step one, you would just have to expand the brackets. The number of times multiplication would be used is 3 times. If you are confused, I attached a diagram in my ‘side notes’ section.
Answer (for question 2):
-5x squared and -12x squared are like terms because they both end in x squared.
Answer (for question 3):
There are no more like-terms.
