3. Find the equation of the line that passes through the points (1, 1) and (3,5). * (2 points)
O y= 2x + 2
O y = 1 - 2x
O y = 2x + 1
O y = 2x - 1

Step-by-step explanation:

Parallel lines have the SAME slope...so for the given formula y = 2x + 1 (given in y = mx + b form)

the slope, m = 2. The slope, m of the 2nd line will be 2.

Use the Point-Slope formula... y - y1 = m(x - x1) to find the equation of the 2nd line by plugging in the values of the given point (4, 3) for x1 and y1 and using the slope, m from the 1st equation

Therefore,y - 3 = 2(x - 4)

y +3 = 2x - 8 distributive (multiply the 2) across the terms in the parenthesis

-3 + 3 isolate the y by bringing the 3 term to the RHS

y = 2x - 5 FINAL ANSWER

add an !

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
