Writing y = mx + b

In the slope intercept equation

 $y\ =\ -\frac{4}{3}x\ +\ 7$  what is the b?

•  $-\frac{4}{3}$  

•  $7$  

•  $-\frac{4}{3\ }x$  

•  $-7$  

Select the equation in standard form:

• $y\ =\ mx\ +\ b$

• $y\ =\ 2x$

• $Ax\ +\ By\ =\ C$

• $y\ =\ ax^2\ +\ bx\ +\ c\$

Select the slope intercept form equation with the

 $y-intercept\ of-4$  and the  $slope\ of\ \frac{1}{3}$  .

•  $y\ =\ -4x\ +\ \frac{1}{3}$  

•  $y\ =\ \frac{1}{3}x\ -\ 4$  

•  $y\ =\ -\frac{1}{3}x\ +\ 4$  

•  $y\ =\ 4x\ -\ \frac{1}{3}$
