The first choice is correct.
in the first function f(x)=3x-2, the smallest value is when x=-1, y=-5, the largest value is when x=0, y=-2, but it doesn't include -2 because there is no = sign.
in the second function, the smallest value of y is when x=0, y=3, the largest value is y=13, but it doesn't include y=13
Answer:
Step-by-step explanation:
-12-(-8)+(-3)= -12+8-3
=-12+-3+8
= -15+8
= -7
The slope intercept form is y = mx + b.
The first thing we have to do here is move the term with the x variable over to the right side of the equation.
-2x + 5y = -15 And we do that by adding 2x to both sides of the equation.
5y = 2x - 15
We then have to get y alone. So we divide 5 on both sides.
The answer is y = 2/5x - 3
-4,2

Answer:
<u>Point-slope form: y-9 = -3(x - 6)</u>
<u>Standard form: y = -3x+27</u>
Step-by-step explanation:
The point-slope form equation is y - y1 = m(x - x1). Because we are trying to find the equation that passes through (6,9), use these values as x1 and y1. In this equation m is the slope and we are also given that the slope is -3. This means that the equation in point-slope form is y-9 = -3(x - 6).
If it is asked for the equation in standard form, some simple moving of terms can accomplish that. Multiply out the -3 and get y-9 = -3x + 18. Add 9 to both sides to get a final answer of y = -3x+27.
