Answer (<u>assuming it can be in slope-intercept form)</u>:
y = x + 4
Step-by-step explanation:
With the given information, we can write the equation of the line in slope-intercept form. Use the slope-intercept formula, 
, and substitute values for 
and 
.
The , or the coefficient of the x-term, represents the slope, so substitute 1 in its place. The represents the y-intercept, so substitute 4 in its place. This gives the following answer:
(Remember that the coefficient of the x-term, 1, is still there. However, instead of 
, we can just write it as 
.)
Answer:
slope of line A= 5/3
slope line B=3/5
they are reciprocals 5/3>3/5
Step-by-step explanation:
the intercepts are 0,5 and -3,0 so 0+3/5+0= the slope
3/5 is the slope
We use proportion in this problem solving.
We know that 100% = 40.00 and 125%=x
I take 125% because the marks the price up 25%. So it is 100%+25%.
100x=40.00×125
x=40.00×125÷100
x=50.00
So the she sells the cell phone at 50.00
So first you multiply 22 to both sides, which cancels 22 from the left side.
This will leave you with x - 3 = -22
Then you add three to both sides, which cancels -3 from the left side.
This will leave you with x = -22 + 3, also simplified to x = -19
Hope this helps.

Answer:
vertex = (4, 3 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = (x - 4)² + 3 ← is in vertex form
with vertex = (4, 3 )
