Answer:

Step-by-step explanation:

y=2x²-5x-7

y=2x+2

2x²-5x-7=2x+2

2x²-7x-9=0

2x²-9x+2x-9=0

x(2x-9)+1(2x-9)=0

(2 x-9)(x+1)=0

x=9/2 ,-1

y=11 ,0

solutions are (9/2,11),(-1,0)

nlexa [21]

Answer:

  1. y=x
  2. y=x-2
  3. y=2x+10
  4. y=5x
  5. y=x+21

Whenever finding a rule, figure out what x+1 relates to in terms of y (aka the slope). Also, figure out the y-intercept (0,<em>y</em>)

<u>Example:</u>

x+1 = y+2.

Slope: 2 ÷ 1 = 2.

The y-intercept is (0,9)

This would make the rule y=2x+9
