See below:

Work Step by Step

(a) Slope-intercept form is \[y=mx+b\], where \[m\] is the slope and \[b\]is the \[y\]-intercept. Consider the provided equation, \[3x+2y=4\] To obtain the equation in the form of \[y=mx+b\] subtract\[-3x\] from both sides of equation as, \[2y=-3x+4\] Then, divide both side of equation by \[2\] as, \[y=-\frac{3}{2}x+2\] Hence, the equation in slope-intercept is,\[y=-\frac{3}{2}x+2\]. (b) Consider the given equation, \[3x+2y=4\]. The slope intercept form of the provided equation is, \[y=-\frac{3}{2}x+2\] Compare it with \[y=mx+b\] gives, \[m=-\frac{3}{2}\]and\[b=2\] Hence, the slope of the equation is,\[-\frac{3}{2}\]and the\[y\]-intercept is,\[2\].
