60 POINTS PLEASE HELP FAST!!!! write the equation of a line in standard form that passes through the points (-4,-1) and (1.5,2)

1 answer:

5 0

You find your slope with the equation

(y2-y1)/(x2-x1)

(-1-2)/ -4-1.5)

(-3)/(-5.5)

.54x is your slope

you then plug that into your equation.

y=mx+b

y=.54x+b

you substitute one of our coordinates.

(-4,-1)

-1=.54(-4)+b

-1=-3.45+b

+3.45

2.45=b

your equation is

y=.54x+2.45

standard form

y-.54x=2.45

Below are two parallel lines with a third line intersecting them 149

Eduardwww [97]

I think x = 31°

I solved it like this

x + 149 = 180

x = 180 - 149

x = 31 °

I hope I helped you^_^

The table shows y as a function of x. Suppose a point is added to this table. Which choice gives a point that preserves the func

Hunter-Best [27]

Answer:

A) (-5,7)

Step-by-step explanation:

Functions and Relations

A set of values A can have a relation with another set B as long as at least one element of A has at least one image in B. Functions are special relations where each element of A (the domain of the function) has one and only one image on B (the range of the function).

By looking at the options, we can see that x=9, x=-8, and x=-1 already have defined values in Y, so if we define another value for any of them the relation will stop being a function. The only possible choice to preserve the function is the option

$\boxed{A)\ (-5,7)}$

If the angles of a triangle are in the ratio 1:3:5, what is the measure of the smallest angle

luda_lava [24]

In a triangle, the three interior angles always add to 180°

x + 3x + 5x = 180
9x = 180
x = 180/9
x = 20

the smallest angle = x = 20°
