Answer 1

Answer:

1) Attached please find the graph of the equation 1/2·y + 2 = 0

2) The values of the y-coordinates for the points are the same, while the values of the x-coordinate of the points increases as we move from left to right

3) The result of substituting the x values of two points on the line in the equation 1/2·y + 2 = 0, gives y = -4, which proves that they are solutions of the linear equation

Step-by-step explanation:

1) The given equation is 1/2·y + 2 = 0

Therefore, the given equation in slope and intercept form, y = m·x + c, can be presented as follows;

1/2·y + 2 = 0  

1/2·y = 0 - 2 = -2

y = -2 × 2 = -4

y = -4

Therefore, by comparing the above equation with the equation for a straight line, y = m·x + c, we have;

m = 0, c = -4

Therefore, the graph is an horizontal line with y-intercept at (0, -4)

2) The relationship of the solutions (points) on of the line have with each other are;

a) The values of the y-coordinates for the points are the same, while the values of the x-coordinate of the points increases as we move from left to right

3) Two points on the line are the points (3, -4) and (33, -4)

With the slope = 0, the linear equation is given as follows;

y = 0·x - 4

For the point (3, -4) we have;

y = 0×3 - 4 = -4

y = -4

For the point (33, -4) we have;

y = 0×33 - 4 = -4

y = -4

Therefore, the two points are solutions of the linear equation 1/2·y + 2 = 0, where y = -4.
