Find the equation of the line shown
liraira [26]

The equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

<h3>What is the equation of a line passing through two given points in a 2-dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)

The graph of the picture shows two clear points (4.5. 0) and (0, 9)

(y - 0) = \dfrac{9 - 0}{0 - 4.5} (x -4.5)\\\\\\(y - 0) = \dfrac{9 }{- 4.5} (x -4.5)\\\\\\-4.5y = 9(x -4.5)\\\\-4.5y = 9x - 40.5\\\\y = -2x + 9

Hence, the equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

The value of the missing length is 20

Let the missing length be x

From Parallel lines and transversal theorem, we have that

If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.

Then, we can write that

\frac{x}{15} =\frac{16}{12}

∴ x = \frac{15\times 16}{12}

x = 20

Hence, the value of the missing length is 20

What is the slope of this skateboard ramp if it rises 1.2 meters above the ground and runs 4 meters horizontally at the base?
Nesterboy [21]
By definition, the slope is the inclination of a line in relation to the horizontal. It can be expressed in degrees, ratios and even in percent. Therefore, you can calculate it by applying the following formula:
 
 P%=(H/L)x100
 
 P% is the slope expressed in percent.
 H is the height (H=1.2 meters).
 L is the length (L=4 meters).
 
 When you substitute these values into the formula P%=(H/L)x100, you obtain the slope of the skateboard ramp:
 
 P%=(H/L)x100
 P%=(1.2 meter/4 meters)x100
 P%=0.30x100
 P%=30%
