Answer:
y = -x + 3
Step-by-step explanation:
The equation of a straight line is generally written as;
y = mx + b
where m is the slope and b is the intercept
To get the slope we use the slope formula
Mathematically, that is;
m = (y2-y1)/(x2-x1) = (-1-2)/2-1 = -3/1 = -1
To get the intercept we equate any of the points to the partial equation that we have;
From;
y = -x + b
2 = -1 + b
b = 1 + 2 = 3
So the equation is;
y = -x + 3
Answer: 5
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Do you have a picture of the table??
You would have the square root symbol (called a radical) over the number 72. But if you mean to simplify it, you can keep in mind that 9 x 3 = 72 and the square root of 9 is 3, so then your answer would be
3(radical)3
Hope that's not too confusing!
