Answer:
Step-by-step explanation:
y=-1
because when y = - 1,
it is an equation of x axis.. hence it will parallel to x axis....
Answer:

Step-by-step explanation:
step 1
Find out the price of 160 begonias, if she bought them separately

step 2
Find out the price of 160 begonias, if she bought them by the flat
Remember that
One flat are 20 plants
so
For 160 plants are needed
160/20=8 flat

step 3
Find out the difference

Y = 2x + 7.....the slope here is 2. A parallel line will have the same slope.
y = mx + b
slope(m) = 2
(-4,7)....x = -4 and y = 7
now we sub and find b, the y int
7 = 2(-4) + b
7 = -8 + b
7 + 8 = b
15 = b
so ur parallel equation is : y = 2x + 15 <==
