Part C Find the values for a and b. Explain or show your reasoning. Answer Part D What is the y-coordinate when x = 0? Explain or show your reasoning. Answer

(a)

and

(b)

Step-by-step explanation:

Given

Solving (a): The values of a and b

First, calculate the slope of the line:

Let c = 4 and d = 1

So, we have:

To solve for the value of b, we apply slope formula

Let c = 2 and d = 1

So, we have:

Substitute 2 for m and ;

Multiply both sides by 2

Add 2 to both sides

To solve for the value of a, we apply slope formula

Let c = 3 and d = 1

Substitute 2 for m and ;

Cross Multiply

Open bracket

Add 4 to both sides

Divide both sides by 2

Solving (b): The value of y when x = 0.

This point is represented as:

Apply slope formula

Substitute 2 for m and  

Cross Multiply

Divide both sides by 2

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
