Answer:
The answer is C
Well lets calculate the slope = the slope which can clearly be seen which is 2x because each time it goes up it goes one to the right so it is 2x
y intercept = where is the y intercept, well clearly seen the y intercept is at 1
so when converted to y=mx+b it is y=2x+1
so slope = 2 and y intercept = 1
