Write an equation in point-slope form of the line through point J(–10, –9) with slope 3.
Alinara [238K]
Use point-slope formula---> y-y1=m(x-x1)
Let y1 equal -9, let x1 equal -10, and let m equal 3 
Plug in and solve
y-(-9)=3(x-(-10)
y+9=3(x+10)
y+9=3x+30
Subtract nine from both sides 
y=3x+21(This is slope form, i might have gone too far)

The price of a coat increased from $78 to $92. What is the price increase percentage?
blagie [28]

Answer:

18%

Step-by-step explanation:

Since the original price is $78 then this is the original 100% of the price. The new price will be marked up x percent and be $92. To find the new price set up a proportion with these values:

\frac{92}{78}=\frac{x}{100}

Solve for the original price by cross multiplying numerator with denominator.

x(78) = 92(100)

78x = 9200

x= 117.9 = 118%

This is 18% more or over the original price.
