Question

Draw the graph of y = 2x + 5

Answer 1

To draw graph, we need to find out some points

y = 2x + 5

for y = 2x + 5

put x = – 1

y = 2(– 1) + 5 = – 2 + 5 = 3

∴ (–1, 3) is a point

put x = – 2

y = 2(– 2) + 5 = – 4 + 5 = 1

∴ (– 2, 1) is a point

Now let us plot the points & join them on graph
