Answer:
see below
Step-by-step explanation:
5x + y=10
Let x = 0 and y = 5
5*0 +5 = 10
0+5 = 10
5 =10
This is not true so (0,5) is not a solution
Slopes of perpendicular lines are opposite reciprocals of each other. The slope of the given equation (which is in slope-intercept form) is 1, the invisible coefficient of x. The opposite reciprocal of 1 is -1, thus the slope of a line perpendicular to the line y = x + 4 is -1.
Hope this helps.
Answer:
The class 35 - 40 has maximum frequency. So, it is the modal class.
From the given data,








MODE
- Most precisely, mode is that value of the variable at which the concentration of the data is maximum.
MODAL CLASS
- In a frequency distribution the class having maximum frequency is called the modal class.
