Answer:
3 - B
4 - D
Step-by-step explanation:
Hey There!
they are asking for the slope in slope intercept form
y = mx + b
where m = slope and b = y intercept
The slope is change in y over change in x
as y goes up 4 x goes up 2
4/2=2 so the slope (or m ) is 2
The y intercept is at point (0,-4)
So the y intercept (or b) is -4
now we add everything together and get that the equation of the line is
y=2x-4
for 4
the best rule is D 2n+2
Why? because the rate of change is 2
and the y intercept is at (0,2) so the best rule would be 2n+2
