-20a divided by 12b would be -1.6
Just use the distributing property and combine like terms. There isn’t a definite answer since it is an expression.
Given that,
Point = (-5,3)
Slope, m = -3/5
To find,
The slope intercept form of the equation of the line.
Solution,
The general form of equation is :
y = mx +b
We have, x = -5, y = 3
So,

The equation is :

Hence, the required equation is
.
The answer for t is 4 and the proportional relationship is 9
