We know that

• Each packet of sweet-pepper seeds costs $2.75.

,

• Each packet of rainbow blend tomato seeds costs $4.25.

,

• The total spending is $46.75.

Based on the given information, we can express the following equation

(a)


2.75x+4.25y=46.75

Where x refers to sweet-pepper seeds, and y refers to blend tomato seeds.

(b) To find the y-intercept, we solve the equation for y


\begin{gathered} 4.25y=46.75-2.75x \\ y=(46.75-2.75x)/(4.25) \\ y=11-0.65x \end{gathered}

The y-intercept is 11 because that's the constant.

(c) To find the x-intercept, we evaluate the equation for y = 0.


\begin{gathered} 2.75x+4.25\cdot0=46.75 \\ 2.75x=46.75 \\ x=(46.75)/(2.75) \\ x=17 \end{gathered}

The x-intercept is 17.

(d) The image below shows the graph
