What is the equation of this line?

Mathematics
1 answer:
jolli1 [7]3 years ago
4 0
Slope-point form:
y=mx b

We need two points to work out the slope; for example in this line we have:
(0,-2)
(4,0)
m=(y₂-y₁)/(x₂-x₁)

m=(0+2)/(4-0)=2/4=1/2

In this line the y-intercept (b)=-2

The equation of the line will be:   y=1/2 x-2

Answer: y=1/2 x-2

In Exercises 17-20, find the value of x so that the function has the given value. 17. f(x) = 8x - 7; f(x) = 17
Nastasia [14]

Answer:

17.) x = 3

18.) x = -5

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3

Step-by-step explanation:

All you really have to do for all of the problems is substitute your value of "x" for the function.

17.) f(x) = 8x - 7; f(x) =17

    17 = 8x -7  ---- substitute 17 for f(x), add 7 on both sides

    24 = 8x ------ divide 8 on both sides

    x = 3

18.)    g(x) = -4x + 7; g(x) = 27

           27  = -4x + 7  substitute 27 for g(x), subtract 7 on both sides

           20 = -4x

            x = -5

Need help please , I know the basic math. how do I solve this?
Mkey [24]
(7/15)/(3/5)
easy
(a/b)/(c/d)=(a/b)(d/c)
invert and multiply (what it does is it cancels the bottom and makes it one)
(7/15)/(3/5)=(7/15)(5/3)=35/45=7/9

answer is C
