Answer: It's a linear equation.</h3><h3>It's not a proportional relationship.</h3><h3>Juanita spend $63 on groceries if she spent $30 on transportation.</h3>
Step-by-step explanation: Given equation y=2x+3.
Where x is the amount she spends on transportation, and y is the amount she spends on groceries.
<em>We can see that given equation is in slope-intercept form y=mx+b.</em>
So, it's a linear equation and y=2x+3 is the relationship between x and y linear.
<em>Also, a linear linear equation represents a proportion relationship if y-intercept is 0.</em>
But for the given equation y=2x+3, y-intercept is 3.
Therefore, it's not a proportional relationship.
Now, in order to find how much would Juanita spend on groceries if she spent $30 on transportation, we need to plug x= 30 in given equation.
Therefore,
y = 2(30) +3 = 60+3 = 63.
<h3>So, Juanita spend $63 on groceries if she spent $30 on transportation.</h3>

<h3>Answer: Choice (1)</h3>
Wayne can buy 2 walking tacos and 4 boxes of popcorn.
====================================================
Explanation:
x = number of tacos
y = number of boxes of popcorn
3x = amount spent on all the tacos only ($3 per taco)
1y = amount spent on all the popcorn only ($1 per box of popcorn)
3x+1y = total amount spent for both food types combined
3x+1y = 10 since Wayne has $10 to spend
The equation solves to y = 10-3x
------------------
If we plugged in x = 2, then,
y = 10-3x
y = 10-3*2
y = 10-6
y = 4
Telling us that x = 2 and y = 4 pair up together. The point (2,4) is on the line y = 10-3x
Since x is the number of tacos and y is the amount of popcorn, this means (x,y) = (2,4) indicates that:
Wayne can buy 2 tacos and 4 boxes of popcorn
This is why the answer is choice (1).
Choice (2) is incorrect because it has the numbers swapped in the wrong spots.
