How do I solve 8, 9, and 10?

Mathematics

Answer:

8)

y-8=m(x+6)\\y-8=\frac{-4}{3}(x+6)\\\\y=\frac{-4}{3}x

9)

y+4.5=mx\\y=15x-4.5

10)

y+1=m(x-1)\\y=-2(x-1)-1\\y=-2x+1

Step-by-step explanation:

We can use the definition of a line:

y-y_0=m(x-x_0)

where y_0 and x_0 co-ordinates of a point on that line, and where m is the gradient of the line.

We can work out the gradient of the line by looking at the differential, or the change in y compared to the change in x.

m=\frac{\Delta y}{\Delta x} = \frac{y_1-y_0}{x_1-x_0}

where (x_0,y_0) and (x_1,y_1) are two distinct points on the line.

Are You guys up for math?? Its 6th grade math though!! so are you ready?? l want help please.

The ratio would be 4:1.

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 64 and 16 is 16

Divide both terms by the GCF, 16:

64 ÷ 16 = 4

16 ÷ 16 = 1

The ratio 64 : 16 can be reduced to lowest terms by dividing both terms by the GCF = 16 :

64 : 16 = 4 : 1

Therefore:

64 : 16 = 4 : 1
