Find the slope of a line parallel to a line containing points (3,-5) and(1,7)
schepotkina [342]

Answer:

Required slope = - 6

Step-by-step explanation:

Parallel lines have same slope.

(x₁ , y₁) = (3 , -5)      &  (x₂ , y₂) = (1, 7)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

        = \frac{7 - [-5]}{1-3}\\\\=\frac{7+5}{1-3}\\\\=\frac{12}{-2}\\\\= -6

Slope of the a line parallel to a line  = -6

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y
IceJOKER [234]

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

The position equation is s = -16t^2 + vot + so where s is height of the object in feet, vo is the initial velocity of the object
Hunter-Best [27]

A.      For this case, let us set the variables:

s = 0 (final destination on the ground)

t = unknown

vo = 0

so = 8000 ft

Using the equation, we calculate for t:

0 = -16 t^2 + 0t + 8000

t = 22.36 s


B.      For this case:

s = unknown

t = 22.36 s

vo = 600 miles/hr = 880 ft/s

so = 0

Using the equation, we calculate for s:

s = -16*(22.36)^2 + 880*22.36 + 0

s = 11, 677.29 ft = 2.21 miles
