The graph below shows the relationship between the number of months different students practiced tennis and the number of matches they won: Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points) Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope. (5 points)

Part A; Y - intercept = 4 matches,

Part B; y = 2x + 4

Part C; 30 Matches Won

Step-by-step explanation:

The y - intercept is about 4 or so, and it represents the number of matches won in tennis. If we were to formulate the approximate equation for this data graph, knowing the y - intercept, let us calculate the slope;

With the slope, let us formulate the equation of this line;

13 months is represented by the x - axis, so let us plug it into the equation that we formulated and solve for y, the number of matches one;

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
