A line has a slope of 2 and a y-intercept of (0, -4). What is the value of y when x=6?

OpenStudy (anonymous):

x is 6, y will be 8 (6,8)

OpenStudy (anonymous):

and you just plugged that into y=mx+b, right?

OpenStudy (anonymous):

yeah! also if you have a graphing calculator, you can put it into y= and do 2nd graph and check on the table. But, without the calculator, you just plug it into y=mx+b .

alright, wasn't sure. Thank you!
