Step-by-step explanation:
2) 5x + y = 2
Rewritting by making y subject of formula:
y = -5x + 2
We need to plot the graph with some points.
By assigning values to x, we get the values of y. Then we plot those points:
when x = -1
y = -5(-1) + 2 = 5+2 = 7
when x = 0
y = -5(0) + 2 = 2
when x = 1
y = -5(1) +2 = -5+2 = 3
when x = 2
y = -5(2) + 2 = -10+2 = -8
Plotting the graph:
