Answer here\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 } =   \frac{-1 -   \frac{1}{4}}{-2 -  3} =  \frac{ - \frac{5}{4}}{-5}= \frac{ - \frac{5}{4}\cdot4}{-5\cdot4} =\frac{-5}{ -20}  =\boxed{ \bf{  \frac{1}{4}}}

The slope is 1/4.

The equation in point-slope form is:
y - (-1) = 1/4(x - (-2))
\boxed{\bf{y + 1 = \frac{1}{4}(x+2)}}

In slope-intercept form, it is:
y + 1 = 1/4(x+2)
\boxed{\bf{y = \frac{1}{4}x - \frac{1}{2}}}

In Standard form it is:
y = 1/4x - 1/2
1/2 = 1/4x - y
Multiply both sides by 4
2 = x - 4y
\boxed{\bf{x-4y=2}}

I hope that helps. :)

the perimeter of a rectangle is 68ft the ratio of the length to the width iss 9:8 what are the dimensions of the rectangle
NikAS [45]

Answer:


Step-by-step explanation:

2 * L + 2 * W = 68  

2*L = 2* 9x = 9x + 9x  

2*W = 2*8x = 8x + 8x  

Since the perimeter is 68  

9x + 9x + 8x + 8x = 68

What is the mapping rule for a 45 degree rotation?
sleet_krkn [62]

Step-by-step explanation:

Imagine a line segment on a coordinate plane that rotates around the origin like a clock hand. If it travels 45° (or any positive degree angle), it will travel in a counterclockwise direction. If it rotates -45° degrees (or any negative degree angle), it will travel in a clockwise direction.

aliya0001 [1]

(A)

P(<em>X</em> < 61.25) = P((<em>X</em> - 55.4)/4.1 < (61.25 - 55.4)/4.1)

… ≈ P(<em>Z</em> ≤ 0.1427)

… ≈ 0.5567

(B)

P(<em>X</em> > 46.5) = P((<em>X</em> - 55.4)/4.1 > (46.5 - 55.4)/4.1)

… ≈ P(<em>Z</em> > -2.1707)

… ≈ 1 - P(<em>Z</em> ≤ -2.1707)

… ≈ 0.9850
