Question 275743
2.1x+3.5y=10.5
3.5y=-2.1x+10.5
y=-2.1/3.5+10.5/3.5
y=-.6x+3 the y interceptis (0,3)
Setting y=0 & solving for x we get the x intercept.
0=-.6x+3
.6x=3
x=3/.6
x=5 the x intercept (5,0)
{{{ graph( 300, 200, -6, 6, -10, 10,-.6x +3) }}} (graph 300x200 pixels, x from -6 to 6, y from -10 to 10, -.6x +3).
