Answer:

y=x+5

Step-by-step explanation:

y-y1=m(x-x1) POINT-SLOPE FORM

Plug in your point and slope

y-3=1(x+2) (The signs flip because of the negative)

y-3=x+2 (SIMPLIFY)

y=x+5 (Move the three. It is now slope int form)

You can check by plugging in -2 for x, and get 3 for y. (it works)

2a+b=-7
5a+b=-13

b=-2a-7
5a-2a-7=-13
3a=-6
a=-2=first number

2(-2)+b=-7
-4+b+-7

Make a conjecture of what the x-intercepts of the function<br> f(x) = (2x - 1)(x + 3) will be.

drek231 [11]

Answer:

x=-3,x1/2

Step-by-step explanation:

f(x)=(2x-1)(x+3)

TI find x intercept/zero substitute

f(x)=0

0=(2x-1)x(x+3)

swap the sides of the equation

(2x-1)x(x+3)=0

when the product of factors equals 0,at least one factor is zero

2x-1=0

x+3=0

solve the equation for x

x=1/2

x+3=0

solve the equation of x

x=-3

The equation has two solution

x=-3

x=1/2

Explain how you could use a number line to show that -4+3 and 3+(-4) have the same value.which property of addition states that

Anna007 [38]

For -4+3,
1. start with zero
2. move to left (-x axis) for 4 units (-4)
3. then move to right (+x axis) for 3 units (+3)

For 3+(-4)
1. Start with zero
2. Move the point to right side by 3 units (+3)
3. then move the point to the left by 4 units (-4)

For both you'll stop at -1.
