Answer:
is the slope and 
is the y-intercept.
Step-by-step explanation:
The slope-intercept form of a line is given as:
Here, the coefficient of 
represents the slope of the line.
The coefficient of is and hence the slope.
y-intercept is the value of 
for which is is 0.
Now, if we put as 0 in the above equation, we get
Therefore, y-intercept is .
Hence, for the line with slope-intercept form , is the slope and is the y-intercept.

Answer:
B. (10,4)
Step-by-step explanation:
Let x be the independent variable and y represents the dependent variable in the graph,
∵Graph represents the direct variation,
⇒ y ∝ x
⇒ y = kx
Where, k is the proportionality constant.
Here, k = 0.4,
⇒ Equation that shows in the graph would be,
y = 0.4x
At (4, 10),
10 = 0.4(4) ( False ),
⇒ (4, 10) is not in the graph.
At (10, 4),
4 = 0.4(10) ( True )
⇒ (10, 4) is on the graph.
At (0.04, 10),
10 = 0.4(0.04) ( false )
⇒ (0.04, 10) is not on the graph.
At (10, 0.04),
0.04 = 0.4(10) ( false )
⇒ (10, 0.04) is not on the graph.
