Negative reciprocal means
-1/4 times x=-1 solve for x
multiply both sides by -4/1
x=-4
so slope=-4
y=mx+b
m=slope, b=y intercpet
y=-4x+b
input 3 for x and -5 for y
-5=-4(3)+b
-5=-12+b
add 12 to both sides
7=b
the equation in slope intercept form is y=-4x+7
that is my standard form
another standard form is
y+4x=7
Answer:
120 baseball cards
Step-by-step explanation:
15 × 2 = 30
30 + 10 = 40
40 ÷ 1/3 = 40 × 3/1 = 120
Therefore there were 120 cards in the back
<em>I just did the inverse of each process starting from the last step and ending at the first</em>

A 40 x 110 rectangle has an area of 4400 sq. ft.
The horse has a 14 ft lead. That makes 14 ft. the radius that the horse can cover.
The formula for the area of a circle is r^2 * PI ( radius squared * 3.14 ).
So the horse can't get to 4400 - ( 14 * 14 * 3.14 ) sq. ft.
