the priority is in slope-intercept variety, that's y = mx + b. m is the slope and b is the y - intercept. start up off via plotting your y - intercept (the factor the place the line meets the y - axis ) b is - 3 for the 1st one. So plot a factor on (0, -3). The slope if a million/2. Slope is purely upward thrust over run. So flow up one (upward thrust) and flow over to the right 2 (run). Plot a factor there. From there proceed going up one and over 2. once you run out of area be certain you flow lower back and do the left factor of the graph. flow lower back on your y - intercept, then flow LEFT 2, down a million. shop doing it till you run out of area. For the 2d, the equation is purely y = mx. there is no b, so it somewhat is 0. Plot a factor at (0,0) then. Then plot the slope factors. Up 5, over 3. Do it any different way as properly. The 0.33 situation is purely y = b, they simply grant you with the y - intercept. So flow forward and plot (0, -4). because of the fact there is no slope, there is no upward thrust or run. So it somewhat is purely a as we communicate horizontal line by using -4 on the y-axis. desire that helped!

looks like an equation to me...with a slope of -1/2 and a y intercept of -3

The number in front of x is always the slope and then -3 is the y-intercept becuase the equation u start with first is
y=mx+b!

first change signs
so it is
y=1/2+(-3)
add it
find common denominator
so it 1/2+(-6/2)
add it
and i got
-5/2

depends on what x=.if x=10 then y=2..etc.you have to know a known value for x or y

2y = x - 6
2y + 6 = x
