Question

How do I️ graph y+2x=3

Answer 1

Y + 2x = 3....put this in y = mx + b form by subtracting 2x from both sides
y = -2x + 3

so u have a slope of -2 and a y int of 3 or (0,3)

ur x int can be found by subbing in 0 for y and solving for x
y + 2x = 3
0 + 2x = 3
2x = 3
x = 3/2 or 1.5....so ur x int is (1.5,0)

so go ahead and plot ur intercepts (1.5,0) and (0,3).....and since u have a slope of -2, start at (0,3)....come down 2 spaces, then go right 1 space....plot that...then down 2 and to the right 1...plot that...keep doing this and u should cross the x axis at (1.5,0)....then connect ur plotted points and u have ur line.
