Step-by-step explanation:

la recta:

$y-yo=m(x-xo)$ (*)

P=(xo,yo)

$m=\frac{Ya-Yb}{Xa-Xb}$

substituindo:

$m=\frac{3-7}{1-3}\\\\m=2$

Seja P=A=(xo=1,yo=3), utilizando a formula (*)

$y-3=2(x-1)\\y=2x-2+3\\y=2x+1$

What is the solution to y-7>3+2y

Alex17521 [72]

Solving:

-7 + y = 3 + 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

-7 + y + -2y = 3 + 2y + -2y

Combine like terms: y + -2y = -1y

-7 + -1y = 3 + 2y + -2y

Combine like terms: 2y + -2y = 0

-7 + -1y = 3 + 0

-7 + -1y = 3

Add '7' to each side of the equation.

-7 + 7 + -1y = 3 + 7

Combine like terms: -7 + 7 = 0

0 + -1y = 3 + 7

-1y = 3 + 7

Combine like terms: 3 + 7 = 10

-1y = 10

Divide each side by '-1'.

y = -10
