Y=-3x+2
y=4x-5
find the y slope. find the x slope.

Both these expression are written in slope-intercept form. y = mx + b

m = slope

b = y-intercept

We can find the slope of each expression by finding what m is in each equation.

y = -3x + 2 -> m = -3

y = 4x - 5 -> m = 4

Remember that m = slope

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,

mrb
