Question

draw the graph of the equation y=3x + 4.find graphically the value of y when x = -1​

Answer 1

Answer:

(-1, 1)

Step-by-step explanation:

Replace all occurrences of x in y = 3x + 4 with -1

y = 3 (-1) + 4

x = -1

Multiply 3 by -1

y = -3 + 4

x = -1

Add -3 and 4

y = 1

x = -1

(-1, 1)
