Answer: -3
Step-by-step explanation:
The slope of a line passing thorough two points (a,b) and (c,d) is given by :-
From the given description, we observe that the line is passing through (1,-1) and (-1,5).
Then , the slope of the graph passing through (1,-1) and (-1,5) will be :
Hence, the slope of this graph= -3
Answer:
-3
The slope is the ratio of the change in y-coordinates to the change in x-coordinates:
... (5 -(-1))/(-1-1) = 6/-2 = -3
The answer is 11d = 121c
Dividing by a fraction is the same as multiplying by the upside-down fraction.
(5/8) ÷ (2/3) = (5/8) ⋅ (3/2) = 15/16
Given the expression
Follow the PEMDAS order of operations
calculate within parentheses
calculate exponents
Multiply and divide (left to right)
Add and subtract (left to right)
Thus,
If you can manipulate the two equations so that they have exactly the same coefficients (e. g., 3x + 4y = 8 and 2x + 4y = 8), then you conclude that the two lines coincide (overlap), and that there are thus infinitely many solutions.
