Which of the following is equation of a line that passes through (-2,1) and (-4,-3)?

ladessa [460]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

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

=======================================

We have the points (-2, 1) and (-4, -3). Substitute:

$m=\dfrac{-3-1}{-4-(-2)}=\dfrac{-4}{-2}=2$

$y=2x+b$

Put the coordinates of the point (-2, 1) to the equation:

$1=2(-2)+b$

$1=-4+b$ add 4 to both sides

$5=b\to b=5$

Finally:

$y=2x+5$

Helena creates two similar rectangles using exactly 100 cm of string. The smaller rectangles width and length are 4 cm by 6 cm r

Misha Larkins [42]

Answer:

The dimensions of the larger rectangle are $24\ cm$ of length by $16\ cm$ of width

Step-by-step explanation:

Let

x-----> the length of the larger rectangle

y-----> the width of the larger rectangle

we know that

$\frac{x}{y}=\frac{6}{4}$ ------> by similar rectangles

$x=1.5y$ -----> equation A

Find the perimeter of the smaller rectangle

$P=2(6+4)=20\ cm$

Find the perimeter of the larger rectangle

Subtract the perimeter of the smaller rectangle from 100 cm of string

$P=100-20=80\ cm$

Remember that

$80=2x+2y$ ------> $40=x+y$ ------> equation B

substitute equation A in equation B

$40=1.5y+y$

$2.5y=40$

$y=16\ cm$

Find the value of x

$x=1.5(16)=24\ cm$

The dimensions of the larger rectangle are $24\ cm$ of length by $16\ cm$ of width
