Question

Draw the graph of the equation y = 3x - 4 . Find geographically
( i ) the value of y when x = -1
( ii ) the value of x when y = 5

Answer 1

Answer:

(i) -7 (ii) 3

Step-by-step explanation:

we have

y=3x-4

1. the value of y when x=-1 , y= -7 , y=3x-4 => y=3×(-1)-4 => y=-7
2. the value of x when y=5 , x=3 , y=3x-4 => 5=3x-4 => 3x=5+4 =>3x=9 =>x=9÷3 =>x=3
