What is the slope of the line that passes through the points (1, 1) and (9, 7)?
5/4, 4/3,4/5,3/4

Step-by-step explanation:

3/4

Step-by-step explanation:

How do you define slope; slope is defined mathematically as M;

M= y2-y1/x2-x1

Where y2=second co-ordinate point of y

y1= first co-ordinate point of y

X2= second co-ordinate of X

X1= first co-ordinate of X

Hence x2=9, xi=1; x2-x1= 9-1=8

Y2=7, y1=1; y2-y1= 7-1= 6

Hence M= 6/8= 3/4

answer: f = 32.2m

step-by-step explanation: that is the answer

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
