Y is usage so set y to 0 and solve for x

y = -10x+100

0 = -10x +100
 subtract 100 from each side:
-100 = -10x

divide both sides by -10

x = -100 / -10

x = 10 hours

Emelina wrote the equation of a line in point-slope form as shown below.
Harman [31]

Answer: y=3x+2

Step-by-step explanation:

Given: Emelina wrote the equation of a line in point-slope form as shown below.

(y+4)=3(x+2)

To write the equation in intercept form, first we multiply 3 inside the bracket values in the right side , we get

y+4=3x+6

Now, subtract 4 from both sides , we get

y=3x+2

Hence, Emelina’s equation in slope-intercept form : y=3x+2
