Question

Draw a graph of y=2x+3 and determine the following graphically
1)value of y when x=-3
2) value of x when y =7​

Answer 1

Answer:

(1) y=2(-3)+3

y=-6+3

y=(-3)

so the value of x=(-3) and value of y=(-3)

(2)7=2x+3

2x+3=7

2x=7-3

2x=4

x=4/2

x=2

Answer 2

Answer:

1) y = -3

2) x = 2

Here is your answer
