Answer:
Explanation:
Given:
To Find:
Value of p=?
Solution:
Before solving this equation, we will use the method of BODMAS which states that we first solve the Bracket then Off then Division then Multiplier then addition and at last subtraction.
Now we will solve the both right and left hand side of the equation
Gruoping the like terms we get,
After solving the both right hand and left hand side of the equation
And we get the value of p as
Answer:
Option A is correct
The linear relationship displayed by the scatter plot is; y=x+10
Step-by-step explanation:
Scatter plot states that a set of points that represent data.
To determine the best equation for a set of points from the given figure.
In general, you can use these steps as follows:
and also try to have the same number of points above and below the line.
To find the equation of linear relationship that displayed by the scatter plot
Using Slope-intercept form:
For any two points and
the equation of line is given by:
where m is the slope and it is given by:
From the figure we choose two points on the line:
i.e, (9 , 19) and ( 15 , 25)
Calculate first slope m :
Now, using slope intercept form to find the equation of line;
or
y-19 = x -9
Add both sides 19 we get;
y -19 + 19 = x -9 + 19
Simplify:
y = x+10
Therefore, the function which best expresses the linear relationship displayed by the scatter plot is; y = x +10
