Step-by-step explanation:
To graph a line we need two points in the line. So, to find two points we will give a value for x and calculate the value of y as:
If x = 0, then:
y = -2x + 1
y = -2(0) + 1
y = 0 + 1
y = 1
If x = 1, then:
y = -2x + 1
y = -2(1) + 1
y = -2 + 1
y = -1
Therefore, we have the points (0, 1) and (1, -1). So using these points we get that the graph is:
