SOLUTION: Find the slope and y-intercept for each line that has a slope and y-intercept. x + 2y = 3

Hi,

The standard slope-intercept form of a line is y = mx + b where m is the slope

 and b is the y-intercept.  The y-intercept is the point where the line crosses

 the y-axis.

.

solving for y in the equation given as an equation for the line: 

x + 2y = 3

2y = -x + 3

y = (-1/2)x + 3

slope of this line is (-1/2)

y intercept is 3

line crosses the y axis at Pt(0,3)
