The rate of getting two heads is
(1/2)*(1/2) = 1/4 = 25%
Intersecting on the y axis means x=0.
Plug x=0 in the equation to find out the y value of the intercept> 0+4y-24=0, y=6
so the both line passes the point (0,6)
two perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other is -b/a
In this case, the line x+4y-24=0, 4y=-x+24, y=-1/4 x + 6, the slope is -1/4, so the slope of the perpendicular line is 4/1.
the equation is y=4x+6
a) Given :
51 pounds of seed can be planted in = 9 acre field.
Per pound of seed = 
We can convert 9/51 in simplest fraction by dividing top and bottom by 3.
We get

<h3>Therefore, 3/17 of an acrs can be planted per pound of seed.</h3>
b) $10 amount = 16 pounds of sugar.
$1 amount = 16/10 = 1.6 pounds of sugar.
<h3>Therefore, 1.6 pounds of sugar she got per dollar.</h3>
M >= 85. The >= sign means greater than or equal to.
