f(x)=2x−1
f(x)=−12x−1
f(x)=−2x−1
The straightline through the points (0, -1) and (-1, 1), represents the equation f(x) = -2x - 1. The correct option is D.
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
For the equation f(x) = -2x - 1, we can see that the slope (m) is -2, and the y-intercept (b) is -1.
To graph this line, we can plot the y-intercept first, which is the point (0, -1) on the y-axis. Then, using the slope of -2, we can find another point on the line by moving 2 units up and 1 unit to the left, which gives us the point (-1, 1). We can continue this process to plot more points on the line, but two points are enough to draw a straightline.
So, we can draw a straight line through the points (0, -1) and (-1, 1), which represent the equation f(x) = -2x - 1.
