Answer:
y= 4x-3
Step-by-step explanation:
y=mx+b
the 4 is your slope so you input it in place of the m, which basically tells you the pattern in witch the line goes. For this one it tells you to go right one and up 4 to get to each point: rise/run = 4/1
The -3 is your y-intercept aka b in the equation above. this tells you where the line will intercept the y-axis. in this case it would be (0,-3).
a helpful tip for doing the slope and plotting your points, first try to locate the intercept and do your rise and run from there.
Ex:
y-inter : (0,-3) rise/run : 4/1
(0+1, -3+4) = (1,1)
(1+1,1+4) = (2, 5)
and so on you can also do it the opposite way to get the rest of your points
(0,-3)
(0-1,-3-4)=(-1,-7)
(-1-1,-7-4)=(-2, -11)
and so on.
