Question 148989
That's a common error. The slope intercept of the line is
<font color="green">y=mx+b</font>
m is the slope while
b is the <font color="blue">y-coordinate</font> of the y-intercept


Take note that the x-coordinate of the y-intercept is always zero. since, it is ON the y-axis.

Solve:

-2x-y=10
Substituting x=0,

-2(0)-y=10
-0-y=10
-y=10
y=-10


Oops! i think you got the wrong y-coordinate. The y-intercept is at (0,-10)
