The slope of the linear equation is 5/2.
How to find the slope?
Here we want to find the slope of the line:
-10x + 4y = -4
Remember that the general linear equation can be written as:
y = a*x + b
Where a is the slope.
To find the slope of our equation, we need to isolate the variable y.
-10x + 4y = -4
4y = 10x - 4
y = (10x - 4)/4
y = (5/2)*x - 1
The slope is 5/2.
