Step-by-step explanation:
To do this :
we know the graph will cross the y axis at -9 (because of the y-intercept)
And we can work out the x-intercept by making y=0 and solving for x.
This gives us 15
Check graph below for the answer
Solving by substitution the answer would be X = 2 and Y = -1
Answer:
The slope is 1
Step-by-step explanation:
y2 -y1 /x2 -x1
10-4/ 3- (-3)
6/6
which reduces to 1
Answer:
The best estimate would be C. 7 ft
Step-by-step explanation:
This is more of a logical question. When you think about a door, 7 inches is out. 7 yards would be 21 ft and that is unusually tall for a door, as is 70 feet.
Answer: " y = -10 . "

The question:
Find the value of "y" when "x" equals 17.
Given the equation:
- x + y = -27 ;
___________________
We plug in the given value: "17" ; for "x" ; and solve for "y" :
- 17 + y = -27 ;
_____________________
↔ y + (-17) = -27 ;
Rewrite as:
y − 17 = -27 ; {since: "adding a negative value" is the same
as "subtracting a positive value."}.
_____________________
Now, we add "17" to each side of the equation;
to isolate "y" on one side of the equation; and to solve for "y" :
y − 17 + 17 = -27 + 17 ;
to get:
y = - 10 .
