Answer:</h2>
y = 
x + 3
<h2>
Step-by-step explanation:</h2>
As shown in the graph, the line is a straight line. Therefore, the general equation of a straight line can be employed to derive the equation of the line.
The general equation of a straight line is given by:
y = mx + c <em>or </em>-------------(i)
y - y₁ = m(x - x₁) -----------------(ii)
Where;
y₁ is the value of a point on the y-axis
x₁ is the value of the same point on the x-axis
m is the slope of the line
c is the y-intercept of the line.
Equation (i) is the slope-intercept form of a line
Steps:
(i) Pick any two points (x₁, y₁) and (x₂, y₂) on the line.
In this case, let;
(x₁, y₁) = (0, 3)
(x₂, y₂) = (4, -2)
(ii) With the chosen points, calculate the slope <em>m</em> given by;
m = 
m = 
m =
(iii) Substitute the first point (x₁, y₁) = (0, 3) and m = into equation (ii) as follows;
y - 3 = (x - 0)
(iv) Solve for y from (iii)
y - 3 = x
y = x + 3 [This is the slope intercept form of the line]
Where the slope is and the intercept is 3

Answer:
Correct option (A).
Increasing our confidence to 97% will <u>increase the margin of error</u>.
Step-by-step explanation:
The confidence interval for population mean is:
The margin of error is:
The margin of error of is directly proportional to the critical value.
So if the confidence level is increased from 95% to 97% the critical value will increase.
- The critical value of <em>z</em> for 95% confidence level is 1.96.
- The critical value of <em>z</em> for 97% confidence level is 2.17.
If the critical values increases the MOE increases.
Thus, on increasing the confidence level to 97% the margin of error will increase.
