Question

The line 2x + 3y = -6 intersects the x axis at (a,0) and the y axis at (0,b) what is a + b ?

Answer 1

2x + 3y = -6 (Subtract 2x from both sides)
3y = -2x - 6 (Divide both sides by 3 to isolate x) which will give you y = -2/3x - 2 and this graphed would cross the x-axis at (-3,0) and the y-axis at (0, -2). So a + b = -5
