Passing through(-1,8) and parallel to the line whose equation is 8x-9y-2=0

notka56 [123]

<h3>Answer:</h3>

y = 8/9x + 80/9

<h3>Step-by-step explanation:</h3>

<u>We are given;</u>

Equation of a line as 8x -9y -2 = 0
Coordinates (-1,8)

We are required to determine the equation of a line parallel to the given line and passing through a point (-1,8)

<h3>Step 1: Determine the Gradient of the given line </h3>

When an equation is written in the form y = mx + c, m is the gradient.
Therefore; we could write the equation 8x -9y -2 = 0 in the form of y= mx + c

9y = 8x -2

y = 8/9x - 2/9

Therefore, the slope, m = 8/9

<h3>Step 2: Determine the equation of the line</h3>

We need to know that parallel lines have the same gradient
Therefore, the slope of the line in question is 8/9
It passes through a point (-1, 8)

We can therefore, determine the equation;

Taking another point, (x,y)

$\frac{y-8}{x+1} = \frac{8}{9}$

9(y-8) = 8(x+1)

9y - 72 = 8x + 8

9y = 8x + 8 +72

9y = 8x + 80

y = 8/9x + 80/9

Therefore, the equation of the line is y = 8/9x + 80/9

To find the height that the rocket has reached, we can use the following equation to calculate distance.
s = ut + 1/2 at²
s - distance - h
u - initial velocity - 64 ft/s x 0.3048 m/ft = 19.5 m/s
a - acceleration, since the rocket is travelling upwards against gravitational acceleration, its said to be deceleration. therefore value is -9.8 ms⁻²
t - time taken - t seconds
substituting values in the equation
h = 19.5 ms⁻¹ x t s - 1/2 x 9.8 ms⁻² x (t s)²
h = 19.5t - 4.9t²
