Find the equation of the line through the points (0, –3) and (4, 5)

vekshin1

Answer:

y=2x-3

Step-by-step explanation:

Hi there!

We are given the points (0, –3) and (4, 5)

We want to find the equation of the line between these points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

To write the equation of the line in this way, we need to first find the slope of the line
The slope can be found using the formula $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We already have 2 points, but let's label their values to avoid confusion and mistakes when calculating.

m= $\frac{y_2-y_1}{x_2-x_1}$

m= $\frac{5--3}{4-0}$

Simplify

m= $\frac{5+3}{4-0}$

m= $\frac{8}{4}$

Divide

m=2

We found the slope of the line.

Here is the equation of the line so far:

y=2x+b

Now let's find b

As stated before, b is the y intercept of the line, which is the point where the line passes through the y axis; the value of x at the y intercept is 0

One of the points we were given (0, -3) is actually the y intercept of the line!

The value of b is the value of y at the y intercept; in this case, b is equal to -3

Now substitute -3 as b in the equation.

y=2x-3

Hope this helps!

What is a correct congruence statement for the triangles shown?

Kamila [148]

Answer:

ΔRHS ≅ ΔNKW

Step-by-step explanation:

We are given that, in the triangles RHS and NKW.

∠H = ∠K

Side HS = KW.

∠S = ∠W

Now, using the ASA congruence criteria, which states that when two corresponding angles of the triangles are equal with the included side between them is equal, then both the triangles are congruent.

Hence, according to ASA criteria, ΔRHS ≅ ΔNKW.

KIM [24]

Answer:

9m²-n²

Step-by-step explanation:

(3m+n)(3m-n)

This is so easy algebraic expression.

Just rewrite as,

$(3m) {}^{2} - n {}^{2}$

Simplifying,

$9m {}^{2} - n {}^{2}$

Jordan trolls a fair dice 216 times how many times would Jordan expect to roll a four

Nikitich [7]

Answer:

Step-by-step explanation:

since a fair die has 6 sides (i.e 6 possible outcomes),

P (rolls a 4 on 1 roll) = 1/6

hence if he rolls the die 216 times, we would expect to roll a 4 for 1/6 of the time. I.e.

expected number of times to roll a 4

= (1/6) x 216 = 36 times.
