Answer:
Solution 1 :-
It is more difficult to run up on slope of 5 because greater slope of a line reflects greater angle it makes with base. That is Surafce with slope 5 is more inclined than slope with \(\frac{1}{5}\).
Solution 2 :-
Slope of line passing through two point is given by \(\frac{y_2-y_1}{x_2-x_1}\)
Given points are ( 2, 0 ) and ( 5, 0 )
∴ Slope of line with given points = \(\frac{0-0}{5-2}\)
= 0
Slope of line is 0.
Solution 3 :-
Given: Slope of line = 2
Line passes throught points ( 1, 2 )( 3, y )
Using formula of slope we get,
Slope of line = \(\frac{y_2-y_1}{x_2-x_1}\)
2 = \(\frac{y-2}{3-1}\)
2 = \(\frac{y-2}{2}\)
y - 2 = 2 × 2
y - 2 = 4
y = 6
Solution 4 :-
This part is same as 2nd.
So slope of line passing through these points is 0 .
