In the given question Y=-(2)/(5)X+3, the slope of the given equation should be found.
The equation of a line is typically written in the format of slope-intercept , y = mx + b, where m represents the slope of the line and b is the y-intercept.
In the equation you provided, y = -(2/5)x + 3, the coefficient of 'x' is the slope of the line given.
So, the slope of the line depicted by the given equation is -2/5 .
This -2/5 is simplified as a decimal.
After simplifying as a decimal, it turns out to be -0.4.
Therefore, the slope of the given line is -0.4.
