Question

Use the same coordinate plane to draw the graphs of the functions. Y=kx-2 if k=1, 0.4,-1

Answer 1

Graphs can be used to represent functions.

See attachment for the graphs of: y =x - 2, y = 0.4x - 2, y =-x - 2

The function is given as: $\mathbf{y = kx - 2}$

When k = 1,

We have:

$\mathbf{y = 1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = x - 2}$

So, the equation is: $\mathbf{y = x - 2}$ when k = 1

When k = 0.4,

We have:

$\mathbf{y = 0.4\times x - 2}$ ----- substitution property of equations

$\mathbf{y = 0.4x - 2}$

So, the equation is: $\mathbf{y = 0.4x - 2}$ when k = 0.4

When k = -1,

We have:

$\mathbf{y = -1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = -x - 2}$

So, the equation is: $\mathbf{y = -x - 2}$ when k = -1

See attachment for the graphs of: $\mathbf{y = x - 2}$, $\mathbf{y = 0.4x - 2}$ and $\mathbf{y = -x - 2}$
