Question

If y = 3x+b intersects y= mx +3 at (2, 3), find the value of b and m.

Answer 1

Answer:

The value of b is -3 and m is 0.

Step-by-step explanation:

You have to substitute the coordinates into both equation in order to find m and b value :

Find m,

$y = mx + 3$

At (2,3),

$3 = m(2) + 3$

$3 - 3 = 2m$

$2m = 0$

$m = 0$

Find b,

$y = 3x + b$

At (2,3),

$3 = 3(2) + b$

$b + 6 = 3$

$b = 3 - 6$

$b = - 3$

Answer 2

Answer:

b = -3

m = 0

Step-by-step explanation:

y=mx+b

3 is the constant
