Write each equation in slope-intercept form of the equation of a line. underline the slope and circle the y-intercept in each equation.

3x+4y–12=0

2x+y=1

2x–y=0

A) slope of equation 3x+4y-12=0 is m= and y-intercept is 3

B) slope of equation 2x+y=1 is m=-2 and y-intercept is 1.

C) slope of equation 2x-y=0 is m=2 and y-intercept is 0.

Solution:

The slope - intercept form equation of line is given as

y=mx+c  --- eqn (1)

Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.

c is the y – intercept which is the value of y at the point where the line crosses the y-axis

a) Given that

3x+4y-12=0    --- eqn (2)

On converting equation (2) in slope intercept form, we get

4y=-3x+12

On comparing equation (3) and (1) we get slope of equation (2) is   and y-intercept is 3.

b)  Given that

2x+y=1           …(4)

On converting equation (2) in slope intercept form, we get

y=-2x+1       …(5)

On comparing equation (5) and (1) we get slope of equation (4) is m=-2 and y-intercept is 1.

C)Given that

2x-y=0           …(6)

On converting equation (6) in slope intercept form, we get

y=2x              …(7)

On comparing equation (7) and (1) we get slope of equation (6) is m=2 and y-intercept is 0.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
