Question

Y = 4x + 9
What is the slope and the y-intercept?

Answer 1

• m = 4
• b = 9

Explanation:

We know that:

• y = mx + b
• y = 4x + 9

If we compare these two equations, we can find the slope and the y-intercept.

=> (y = mx + b) = (y = 4x + 9)

We can clearly see that 'm = 4' and 'b = 9'.

Conclusion:

Therefore:

• m = 4
• b = 9

Hoped this helped.

Answer 2

y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9
