A line in the xy-plane that passes through the coordinate points (3, -6) and (–7, –4) will never intersecta line that is represe
anyanavicka [17]

Answer:

option A

Step-by-step explanation:

given coordinate (3, -6) and (–7, –4)

to find the equation of line

slope of the line passing through both the point will be

               m = \dfrac{y_2-y_1}{x_2-x_1}

               m = \dfrac{-4+6}{-7-3}

               m = -\dfrac{2}{10}

equation of line

( y - y₁ ) = m ( x - x₁ )

y + 6= -\dfrac{2}{10}(x - 3)

x + 5 y = -27

line which will not intersect will be parallel to it so option A has same slope as our line equation i.e. -1/5

hence, correct answer is option A

Jacob attempted the third problem above but when checking his work realized he made a mistake. Identify what Jacob’s mistake was
Sloan [31]

Answer:

When solving, Jacob did not distribute properly.

Explanation:

Let's talk about 5(x + 2). The correct distribution would be 5x + 10. Jacob distributed 5 into x correctly and got 5x, however he did not distribute the 5 into 2 properly. It should have been 10, however it stayed as 2.

Jacob should be more careful when distributing, and make sure to distribute into EVERY term inside the parentheses.
