Answer:
y=-2+4
Step-by-step explanation:
we know the y intercept is four, so we can plug that into y=mx+b
so far we know y=mx+4
and the equation for finding slope is
so let's find two points on the graph
let's make it easy on ourselves and use the points laid out for us
(0,4) and (2,0)
solving that would come out to be
simplified, that would be -2
now that we know the slope, we can put them into slope-intercept form
y=-2+4
Answer:
b = 125
Step-by-step explanation:
Given a varies directly as then the equation relating them is
a = k ← k is the constant of variation
To find k use the condition a = 3 , b = 64 , then
3 = k = 4k ( divide both sides by 4 )
= k
a =
← equation of variation
When a = , then
=
( multiply both sides by 4 to clear the fractions )
15 = 3 ( divide both sides by 3 )
5 = , then
b = 5³ = 125
