We know that in order to solve a math problem, we need an equation. Luckily there's an equation to find the slope and intercept of a (straight) line!

Because of the equation:

Y = mx + b

You can use it to find the Y intercept, and then therefore slope (or the other way around)!

First, look at the point where the line meets with the y axis.

It's not clear, but it's 7.

That's your 'Y intercept'. Easy!

Then, to find the slope. There are a couple of ways to find it, but I'll show you the one using the y = mx + b equation.

In the equation, 'b' represents the Y intercept. Since we already know our Y intercept on the graph is 7, we can plug that into the equation.

Y = mx + 7

What's m? M is the slope of the line. In order to find this, we need more numbers to work with. Numbers from the line's coordinate points.

Since coordinates in a graph have x and y, we can plug in any coordinate from the graph's line into our equation (y = mx +7).

I choose...this point (points at random coordinate on line).

(3, 10) aka (x, y)

It's on the line, right? So it will be a reliable x and y.

Put the numbers in...

10 = 3m + 7

This looks a bit easier, right? Now we solve for m (the slope)!

Combine like terms.

10 - 7 = 3m

Divide the 3.

3/3 = m

m = 1.

That's your slope!

So, taking the solution, we can determine that the slope of the line is 1, and the intercept of the line is 7.

Y = x + 7

Hope it helps! This is the most I can do for you :)

Find the values of x and y in the parallelogram when AB=x^2-18, CD=7x, mD=(5y+31), mB=96
Fynjy0 [20]

Greetings, I Am BrotherEye

Answer:

AP = CP, BP = DP; sample answer: If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram, so if AP = CP and BP = DP, then the string forms a parallelogram. ALGEBRA Find x and y so that the quadrilateral is a parallelogram. BP = DP, then the string forms a parallelogram.

Lenny rolls two number cubes. What is the probability that the sum of the numbers Lenny rolls is either 4 or 7?
Mashutka [201]

Probability of an event =


(number of ways the event can happen) / (total number of possible outcomes) .


Well, the total number of possible outcomes is easy. It's


(6 possibilities for the first cube) x (6 possibilities for the 2nd cube)


= 36 total possible ways for two cubes to roll.


Now, how many of those possibilities show either 4 or 7 ?


Well, here's how a 4 can come up:


1 . . . 3

2 . . . 2

3 . . . 1


and here's how a 7 can come up:


1 . . . 6

2 . . . 5

3 . . . 4

4 . . . 3

5 . . . 2

6 . . . 1 .


So there are 9 ways all together for Lenny to be successful.


The probability is (9/36) .


That's 1/4 , or 25% .

Given: circle k(O), m<br> LM<br> = 164°<br> m<br> WK<br> = 68°, m∠MLK = 65°<br> Find: m∠LMW
Semenov [28]

Let P be a point outside the circle such that triangle LMP has legs coincident with chords MW and LK (i.e. M, W, and P are colinear, and L, K, and P are colinear). By the intersecting secants theorem,

m\angle LPM=\dfrac{m\widehat{LM}-m\widehat{WK}}2\impliesm\angle LPM=48^\circ

The angles in any triangle add to 180 degrees in measure, and \angle MLK\congruent\angle MLP and m\angle LMW=m\angle LMP, so that

m\angle MLK+m\angle LPM+m\angle LMP=180^\circ

\implies\boxed{m\angle LMW=67^\circ}
