Answer:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Let X the random variable that represent points in a game of bowling of a population, and for this case we know the distribution for X is given by:
Where 
and 
We know that the value for Renee is X=175 and the z score obteined was Z=2.
Solution to the problem
And the best way to solve this problem is using the normal standard distribution and the z score given by:
We are interested on the value of 
and we can solv for it:
And replacing the values we have:
y = 6x + 6 is a system of linear equations for the graph.

Explain about the linear equations?</h3>
If a variable's maximum power is always 1, an equation is said to be linear. As a one-degree equation, it also goes by that name. An equation with one variable that has the usual form Ax + B = 0 is a linear equation. A coefficient, B is constant, and x is a variable in this situation.
Ax+By=C represents a two-variable linear equation in its standard form. As an illustration, the conventional form of the linear equation 2x+3y=5 It is rather simple to locate both intercepts when an equation is stated in this way (x and y).
First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable).
Slope = y2- y1 /x2- x1
if these points are x (0,-6) y (1 ,-5)
1 +5/ 0 +6 = 6
Equation for the line through (0, -6) and slope is slope = (6),
y - y' = m(x - x')
y - 6 = (6)(x- 0) (x- 0)
y - 6 = 6x
y = 6x + 6
