Write each equation in slope-intercept form of the equation of a line. underline the slope and circle the y-intercept in each equation. a) 3x+4y–12=0b) 2x+y=1

(a ) slope = - and y- intercept = 3

(b ) slope = - 2 and y- intercept = 1

The equation of a line in slope- intercept form is y = mx + c

where m is the slope and c the y- intercept

Rearrange each equation into this form

(a ) 3x + 4y - 12 = 0 ( subtract 3x - 12 from both sides )

4y = - 3x + 12 ( divide all terms by 4 )

y = - x + 3 ( in slope- intercept form )

with slope m = - and y - intercept c = 3

(b ) 2x + y = 1 ( subtract 2x from both sides )

y = - 2x + 1 ( in slope- intercept form )

with slope m = - 2 and y- intercept c = 1
