Its slope is -3 so we got
y=-3x+b
and the graph passes through (1,1)
so we got b=4
the equation is y=-3x+4
Hope this will help
11.45... to solve it, you add all of the numbers and then divide by the total number of numbers. so 126 divided by 11
This looks like "half" a property. I'm assuming you mean something that looks like this:
IF a + b = a + c, THEN b = c. In the expression in your problem, the role of a is being played by 7. The role of b is played by (4 + 6), and the role of c is played by n.
The conclusion would be that 4 + 6 = n.
But you asked about what the property is called. The likely name is the subtraction property of equality. How did we go from a + b = a + c to the conclusion b = c? We subtracted a from both sides of the equation.
The answer is y= -x/3 if you need it in slope intercept form
