If that coordinate is reflected along the x-axis, the image will be (2,1).

Answer with explanation:

The Meaning of reflection of a point through any of the axis states that,the perpendicular distance of a point from either of the axes chosen as line of reflection from Image and Preimage is constant.

⇒Preimage = (2, -1)

Marking the point in x y Plane and then Plotting it's reflection in x y plane

⇒ Image = (2, 1)

In the first Quadrant.

Find the slope of the line through each pair of point

Rashid [163]

The slope of the line passes through (-6, 3) and (1, 5) is $\frac{2}{7}$

<u>Solution:</u>

Given, two points are (- 6, 3) and (1, 5)

We have to find the slope of a line that passes through the above given two points

Slope of a line that pass through $\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right)$ is given as:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text { Here, in our problem, } x_{1}=-6, y_{1}=3 \text { and } x_{2}=1, y_{2}=5$

$\text { Slope } m=\frac{5-3}{1-(-6)}=\frac{2}{1+6}=\frac{2}{7}$

Hence, the slope the line that passes through the given points is $\frac{2}{7}$

12. Simplify:<br> 5x + 3y - 2y + 3xy + 5xy - 10x

Serggg [28]

Hey there!

$\textsf{5x + 3y - 2y + 3xy + 5xy - 10x}$

$\textsf{Combine like terms}$

$\textsf{(5x - 10x) + (3y - 2y) + (3xy + 5xy)}\\\mathsf{5x - 10x = -5x}\\\mathsf{3y - 2y = 1y}\\\mathsf{3xy + 5xy= 8xy}\\\boxed{\boxed{\mathsf{Answer: \bf{8xy-5x+y}}}}\huge\checkmark$
