Line of symmetry is the line which cuts the figure into two same halves

or we can say that which passes through the figure such that it makes one half the mirror image of the other half

So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves

So

y=-2

A painting measure 40 cm by 35 cm how many squared cm does its surface cover
miskamm [114]

Answer: Its surface covers  1400 cm²

Explanation:

Since the length of painting = 40 cm

Breadth of painting = 35 cm

Since we know that area of rectangle is product of dimensions.

∴ Area of painting = length × breadth

∴ Its surface cover  1400 cm².

Need help with this :(
emmainna [20.7K]

Answer:

B.    m = \frac{3}{2}, y-int = 3

Step-by-step explanation:

To find the slope of the line, we need to plot two points

(2, 6) (-2, 0)

m = slope

Then use the Slope-Formula to Solve for the slope

m = \frac{y2-y1}{x2-x1}        

m = \frac{0-6}{-2-2}

m = \frac{-6}{-4}

m = \frac{6}{4}

m = \frac{3}{2}

The Slope is \frac{3}{2}

The y-intercept is 3 because the line is going 3 units upwards on y axis!

Equation: y = 3/2x + 3

Slope: 3/2

y-intercept: 3
