Write the equation of the line in slope intercept form that passed through (1, 4) and (3, 18)
1 answer:
Answer:
y=7x+11
Step-by-step explanation:
to find the slope we need to do which is
or 7.
then, we put this into point slope form (y-y1)=m(x-x1).
y-4=7(1)
we make the x value 0 in order to find the y-intercept.
y=11 since we multiply 7 by 1 to get 7, and add 4 onto both sides.
then we put the slope and the y-intercept into slope intercept form and get y=7x+11.

The complete question in the attached figure
the statements are
1) It makes less than plant B
2) It makes the same as plant A
3) It makes more than plant C
we know that
<span>analyzing the graph
</span>plant A
for x=40 y=100
for x=50 y=200
that means
the production in 10 days is 100 widgets
then
the production in 60 days will be 6*100----> 600 widgets
so
plant A production > plant fourth production
plant fourth production < plant A production
plant B
for x=40 y=0
for x=60 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
so
plant B production < plant fourth production
plant fourth production > plant B production
plant C
for x=20 y=0
for x=40 y=100
that means
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
plant C production < plant fourth production
or
plant fourth production > plant C production
therefore
the answer is
3) It makes more than plant C

therefore
the answer is
3) It makes more than plant C
