Ok soo

First substitute the value for x Ok x=23/7 + 3/7 y. 2x-4y=-8

Second solve the equation 2(23/7 +3/7 y) -4=-8

Third substitute the value of y do y=51/11

Forth solve the equation X=23/7 +3/7 x 51/11

Fifths the possible solution is x=58/11

Sixth check the solution (x,y)=(58/11, 51,11)

Seventh simplify 7x58/11-3x51/11=23. 2x58/11-4x51/11=-8

The ordered pair is a solution 23=23. -8=-8

(x,y)=(58/11, 51,11)

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Find the slope and y-intercept of the data
Vlad1618 [11]

Answer:

slope: 5

y-intercept: 3

therefore y=5x+3

Step-by-step explanation:

the slope is the value that is changing; as time passes the price increases by $5 per hour

the y-intercept is where the function crosses the y-axis (when x is 0); so when no time has passed.
