1. Solve by graphing. Check each solution.
a) y=x-3 b) y=2x-1 c) x+3y=2 d) 3x+2y=6
y=3-x y=-x+5 x-y=6 y=4-x
===========================================
a)y=x-3
slope = 1/1
y-intercept = -3
==========================================
b) y=2x-1
slope = 2/1
y-intercept = -1
===========================================
c) x+3y=2
First put this in slope-intercept form; y=mx+b
subtract each side by x;
3y=-x+2
now divide each side by 3;
y = -1/3x + 2/3
slope= -1/2
y-intercept = 2/3
Think you can do the rest?
Just remember, if the equation is not in slope-intercept form, you need to put it in that form.
Then identify the slope and y-intercept, plot the point on the y-axis and use the slope to find the next point, then draw the line.
