Answer:
The slope of the line is -5/4
Explanation:
19) = Solution :-
5x+4y = 20
Let's keep x's value 0,
so
we get,
5x+4y = 20
or, 5×0+4y = 20
or, 4y = 20
so, y = 5
one coordinate we get (0,5)
Again
Let's keep x's value 4,
we get,
5x+4y = 20
or, 5×4+4y = 20
or, 20+4y=20
or, 4y = 0
so, y = 0
Another coordinate, we get (4,0)
now
slope(m) = (y2-y1)/(x2-x1)
= (0-5)/(4-0)
= -5/4
