Answer:
m=-2 b=0
Step-by-step explanation:
first, in order to understand anything, you gotta know what y=mx+b means :)
first, m is just there so you can substitute it for a number. x represents the slope, and b represents the y-intercept, which you also substitute for a number.
so in y= -2x, there's no y intercept, because there is no number that represents the y intercept.
so if we use y=mx+b, we can just substitute the numbers.
which would be, y= -2.
