Question 693711
Solve
...
solve for y
-2x - y = -3 ==> isolate the y variable
-2x + 3 = y
or better as
{{{highlight_green(y = -2x + 3)}}}
...
Graph
...
Plot the intercepts and draw a line through them
y-intercept can be read from the slope-intercept format of y=mx+b as b
so, in the case of y=-2x+3, the y-intercept is 3
plot (0, 3)
x intercept is where y = 0, so set the equation equivalent to 0
0 = -2x + 3
-3 = -2x 
x = {{{3/2}}}
plot ({{{3/2}}}, 0) or (1.5, 0)
...
{{{graph(300,200,-10,10,-10,10,-2x+3)}}}
