What is the point stope form of a line that has a stope of 3 and passes through point (1, 4)? A) y-4=3(x-1)
B) 1-y=3(x-4)
C)y1-4=3(1-x1)
D) 1-y1=3(4-x1)

idk this answer sorry cant on this one.

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
