Graph 9y=−8x+12. is it a positive slope?

Mathematics

IRISSAK [1]4 years ago

9y=-8x+12 // Divide y by 9.

y= -8/9x+12

It is NOT a positive slope, because -8/9x is negative.

Just isolate y! Since the slope-point formula is y = mx + b, looking at your m determines if it's negative or positive! You can always graph the equation to check, but it's usually easier to look at the formula.

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%

Simplify the expression. Write the answer using scientific notation.<br> (9x10^2)(2x10^10)
Andrews [41]
(9 x 10^2)(2 x 10^10)
(9 x 100)(2 x 10,000,000,000)
(900)20,000,000,000) = 1.8e +13
