If $(3, b)$ is a point on the graph of localid="1646062158338" $y = 4 x + 1,$ what is b ?

Short Answer

Expert verified

The value of $b$ is $13$ .

Step by step solution

01

Given information

The given point is $(3, b)$ .

The given equation is $y = 4 x + 1$ .

02

Determine the value of b

Substitute $3$ for $y$ , $b$ for $x$ in $y = 4 x + 1$ .

$\begin{array}{rcl} b & = & 4 (3) + 1 \\ = & 12 + 1 \\ = & 13 \end{array}$

03

Write the conclusion

The value of $b$ is $13$ .
