Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m =
, thus
y =
x + c ← is the partial equation
To find c substitute (- 4, - 9) into the partial equation
- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7
y =
x - 7 ← equation of line
The slope is 1.
Every time it goes up 1, it goes to the right 1.
Anything to the 0 power is 1
and 1 to the any power is 1
so x can be any number
