The answer would be less. Hope this helps. :)
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
Since you know:
m = -2
b = 5 Substitute/plug it into the equation
y = mx + b
y = -2x + 5
The domain of the function in this case are all the values that the axis of the x takes.
We have then:
The domain is x from -4 to infinity.
Equivalently:
x: [- 4, inf)
x> = - 4
Answer:
x> = - 4
