Answer:
The solution to this question would be
f(x)=−23x+4.
I got this answer by first using the slope formula, which would result into 0−46−0, for which the answer would be −23. Then, the y-intercept could be found easily, since you already have it., which is (0,4). Since the format for all linear equations are y=mx+b, in which b means the y-intercept and m means the slope.
