Answer: y= -1x - 5  

Step-by-step explanation:

The equation has to be in slope-intercept form which uses the formula

y=mx+b   where m is the slope and b is the y-intercept.

So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.

the x coordinate is -7  and the y coordinate  is 2

2 = -1(-7) + b    

2 = 7  + b  

-7   -7

b = -5  the y intercept is -5

Now the equation will be y= -1x - 5

Sav [38]
Answer: 180cm


Explanation:

The area of a triangle is 1/2(b)(h).
The height of the triangles is 12cm and the base is 6cm.

1/2(6)(12) = 36cm
Multiply by 4 = 144


For square: 6 • 6 = 36cm


144cm + 36cm = 180cm
