If a system of linear equations has infinitely many solutions, then the graph of the system is:

a. intersecting lines
b. perpendicular lines
c. the same line
d. parallel lines

answer: 1+1

step-by-step explanation: 1+1 is at least 2

step-by-step explanation:

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
