Y = 6x − 4
Kamila [148]

Answer:

Part B: \displaystyle [1, 2]

Part A: Set both equation equal to each other by Substitution, since our <em>y-values</em> are already given to us.

Step-by-step explanation:

6x - 4 = 5x - 3

- 6x + 3 - 6x + 3

____________

\displaystyle -1 = -x; 1 = x

Plug this coordinate back into the above equations to get the <em>y-coordinate</em><em> </em>of 2.

<em>y</em><em> </em><em>=</em><em> </em><em>mx</em><em> </em><em>+</em><em> </em><em>b</em><em> </em>[where<em> </em><em>b</em><em> </em>is the y-intercept and the rate of change (slope) is represented by <em>m</em>]

\displaystyle y = 5x - 3; [0, -3]; 5 = m \\ y = 6x - 4; [0, -4]; 6 = m

I am joyous to assist you at any time.
