Line m in xy plane contains the points (2,4) and (0,1) which of the following is the equation of M
HACTEHA [7]

Answer:

The equation of line M in slope intercept form is    y=\frac{3}{2}x+1

The equation of line M in standard form is  3x-2y=-2

Step-by-step explanation:

step 1

Find the slope of line M

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(2,4) and (0,1)

substitute

m=\frac{1-4}{0-2}

m=\frac{-3}{-2}

m=\frac{3}{2}

step 2

Find the equation of the line M in point slope form

y-y1=m(x-x1)

we have

m=\frac{3}{2}

point\ (0,1)

substitute

y-1=\frac{3}{2}(x-0)

y-1=\frac{3}{2}x ----> equation in point slope form

step 3

Find the equation of line M in slope intercept form

y=mx+b

Isolate the variable y in the equation of the line in point slope form

y-1=\frac{3}{2}x

Adds 1 both sides

y=\frac{3}{2}x+1

step 4

Find the equation of the line M in standard form

Ax+By=C

where

A is a positive integer

B and C are integers

we have

y=\frac{3}{2}x+1

Multiply by 2 both sides

2y=3x+2

3x-2y=-2 ---> equation in standard form

A rectangular painting by Leonardo da Vinci measured 62cm along its diagonal. If the painting has a height of 42 cm how wide is
IRINA_888 [86]

ANSWER

45.6cm to the nearest tenth.

EXPLANATION

The diagonal of the rectangular painting is 62cm.

The height of the painting is 42 cm.

The height of the painting h , the diagonal, and the width of the painting forms a right triangle with the diagonal being the hypotenuse.

From the Pythagoras Theorem,

{w}^{2}  +  {42}^{2}  = {62}^{2}

{w}^{2} = {62}^{2} -  {42}^{2}

{w}^{2}  = 2080

{w} =  \sqrt{2080}

w = 4 \sqrt{130}

The width of the painting is 45.6cm to the nearest tenth.
