So what you need to do is find the slope and y-intercept. Then, you write it in y=mx+b form. m=slope, b=y-intercept. So in this case, 17/3 is the slope, and -26 is the y-intercept. Hope this helps :)

Answer:

answer: 1) false 2) true 3) true 4) false

Step-by-step explanation:

A: pass (0,0) (12,6)

slope: 6/12 = 1/2

y = 1/2 x

x=1 y= 1/2

B: pass(0,0) (4,6)

slope: 6/4 = 3/2

y = 3/2 x

y=1 x= 2/3

Answer:

$(x - y)(x + y + 1)$

Step-by-step explanation:

$x(x + 1) - y(y + 1)$

Lets expand it.

$= > {x}^{2} + x - {y}^{2} - y$

Lets re-arrange it.

$= > {x}^{2} - {y}^{2} + x - y$

$= > (x + y)(x - y) + 1(x - y)$

Lets take (x - y) common.

$= > (x - y)[(x + y) + 1]$

$= > (x - y)(x + y + 1)$
