Answer with explanation:
The equation of line in Slope intercept form is:
⇒ y= m x +C
y= x tan (Angle made by line with positive Direction of X axis) +C(Y-Intercept)
It is given that, graph of the line appears to slant downward from left to right.
⇒It means ,the angle that the line is making with X axis should be:
90°<Angle<180°
as i have drawn the line about the given information.
⇒Tan (90°< Angle <180°)= Negative
So, we can say that slope of line will be Negative.
