Answer:
y = -2x + 3
Step-by-step explanation:
The slope-intercept formula for a line is y = mx + b where m is the slope and b is the y intercept. Therefore, just sub -2 for m and 3 for b.
Answer:
The inverse is 
(x) = 
Step-by-step explanation:
(By the way, (x) is f negative one of x, like f(x), but inverse)
f(x) = 
- 4 is the same as y = - 4
y = - 4 start with the equation.
x = 
- 4 switch x and y.
x + 4 = add 4 to both sides.
= y square both sides.
(x) = change y to the inverse f(x) format.
I hope this helps! :)
Answer:
B
Step-by-step explanation:
-5x = y - 5 (1)
-2y = -x - 21 (2)
Change x to the left hand side of equation (2)
x = 2y - 21 (3)
Multiply (1) by 2 times:
-10x = 2y - 10 (4)
Use (4) - (3)
-10x = 2y - 10
- x = 2y - 21
-11x = -10 + 21
-11 x = 11
x = -1
Apply x = -1 in (1)
-5*(-1) = y - 5
5 = y-5
y = 5+5
y = 10
So x = -1
y = 10
