7. D
8. D
9. D
10.C
for 7 & 8 you use the equation

your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation

plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
Answer:slope-0.75 y intercept 1
Step-by-step explanation:
Let x represent the number of plants that they will sell in five hours
We were told that the garden store sells six plants per hour. This means that
6 plants = 1 hour
then,
x plants = 5 hours
By cross multiplying, it becomes
x * 1 = 6 * 5
x = 30
They will sell 30 plants in 5 hoursx
