**Answer:**

explanation below

**Step-by-step explanation:**

line is parallel

so you know that the slope will be the same as the equation provided, so for the first question, the slope is -6

line is perpendicular

the slope will be the negative reciprocal (imagine the number as a fraction if not already, then flip it upside down or switch the top and bottom) and add a negative sign. For the second one, the slope will be -3/2

to find the y intercept, you will add or subtract a number to the x value to get that value to equal 0, then you will multiply that number (it will be negative if you subtracted) to the slope, and that will be your y value. So your y intercept that you found should look like this (0,y) with the y value being whatever you just found.

with the format of slope intercept form y=mx+b you can now substitue your values in with m being the slope and b being the y value of your y intercept.

**Answer:**

A^2 means a*a

**Step-by-step explanation:**

A^2 = 5^2=5*5=25

3a^2=3*5^2=3*25=75

A^2+7=5^2+7=25+7=32

Answer:

4 11/16 m²

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

From the question:

Length = 1 1/4 m

Width = 3 3/4m

Area of the rectangle =

1 1/4 m × 3 3/4 m

= 5/4 m × 15/4 m

= 75/16 m²

= 4 11/16 m²

Area of the rectangle = 4 11/16 m²
