Answer:

Step-by-step explanation:
The slope-intercept form is
, where m is the slope of the line and c is where the line crosses the
-axis.
To calculate
we can use the formula
where
is the difference in
between two points and
is the difference between
.
Information we can get from the graph given:
. Since
is the point at which the line crosses the
-axis.
To find
let's get two points from the graph.
Point 1: 
Point 2: 
Now use the equation
.
.
Now we have
and
, let's put them back into the general equation.

1) 18 because you need to divide 36÷ 3 because there are 3 daffodils.
