Find y if x=15 if y is 6 x=30

Len [333]

I'm not sure if this question was correctly transcribed but is it suppose to read find if x=15, find y = 6x+30 ?

If so then y = 120

The way it is written now, If x = 15 then 6x cannot equal 30 which is why I asked. Sorry if I'm not understanding the question.

What is the point slope form of f(-3)=16 and m=25, Explain please

Firlakuza [10]

Answer:

$y - 16 = 25(x + 3)$

Step-by-step explanation:

The equation of a straight line in point slope form is given by:

$y-y_1=m(x-x_1)$

We were given that f(-3)=16, this means that the point (-3,16) is a point on this line.

Also the slope of this line is given as m=25.

We substitute the points and the slope to get:

$y - 16 = 25(x - - 3)$

This simplifies to:

$y -16 = 25(x + 3)$
