Question 705748
I think you meant to type Y = 4/5X - 10
--------------------
The standard eqaution of a line is Y = mX = b
Where m is the slope and b is the Y-intercept.
So yes, (0,-10) is the Y-intercept.
--------------------
The X intercept is found when Y is equal to zero.
{{{0 = (4/5)X - 10}}}
Add 10 to both sides
{{{10 = (4/5)X}}}
Multiply both sides by 5/4
{{{(5/4)*10 = cross((5/4)*(4/5))*X}}}
Simplify
{{{highlight(12.5 = X)}}}
The x-intercept is (12.5,0)
