You could just put 0 for a and b.
It would work.
Answer:
The derivative is
Step-by-step explanation:
The function is given by
Differentiate with respect to x, we get
-4 is what you put on both sides Bc it’s half of b
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
