Y = x + b.
-4 = 2 x (-3/2) + b. -4 and 2 because of (2, -4). 2 is x and -4 is y.
b = 7.
Therefore, -4 = -3/2 + 7.
The <em><u>equation of a straight line</u></em> is an equation that comes in the form of an algebraic equation. It is also referred to as <u>Slope - Intercept form.</u> It can be represented using the equation below:
Equation : y = mx + c
where:
<u><em>m = Gradient</em></u>
<u><em>c = Slope of the line</em></u>
The equation that shows how the price of a personal pizza y, depends on the number of toppings x is y = 7 + x
This question can be solved and represented using the equation of a straight line.
Let's represent
- y = price of a personal pizza
- The price for a plain cheese pizza = $7
- The price for each of the toppings = $1
Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x is written as:
y = $7 + $1 * x
y = 7 + x

Answer:
3
Step-by-step explanation:
Segment BC corresponds to segment DF. The length of BC is the distance between coordinates (0, 2) and (3, 2). These points are on the same horizontal line (y=2), so the distance between them is the difference of their x-coordinates: 3 - 0 = 3.
