Question

Complete the following activity to draw the graph of equation y = 2x + 1​

Answer 1

Answer:

See the attachment.

Explanation:

Given equation,

$\implies \: y = 2x + 1$

In the given graph one point is given i.e., (0, 1)

We need to calculate further, So,

For, $x = 1$

$\implies \: y = 2x + 1$

$\implies \: y = 2(1) + 1$

$\implies \: y = 2 + 1$

$\therefore \boldsymbol{ y = 3}$

Second point is (1, 3)

Furthermore,

for, $y = -3$

$\implies \: - 3 = 2x + 1$

$\implies \: - 3 - 1 = 2x$

$\implies \: - 4 = 2x$

$\implies \: - \dfrac{4}{2} = x$

$\therefore \boldsymbol{x = - 2}$

Third point is (-2, -3)
