Y = 2x + 9

2 is the slope which is rise over run or y2 - y1 over x2 - x1

9 Is the y intercept

Answer:

y = -2x + 9

Step-by-step explanation:

So we know that the line is going down, so that means that slope will be negative. Additionally we know that the y-intercept is 9 because that's where the line crosses the y-axis.

To find slope based on the graph, you can start from the left most point and do rise/run until you get to the next point. In this case, you'd start from (0,9) go down 2 units and over to the right 1, so your Slope is -2/1 or just -2.

So it would be written as y = -2x + 9.

Hope this helps :)

In triangle PQR, angle P is congruent to angle R and the measure of angle Q is twice the measure of angle R. Find the measure of
castortr0y [4]
∠P=∠R, ∠Q=2∠R
the three angles make a total of 180, so
∠P+∠R+∠Q=180
∠R+∠R+2∠R=180
∠R=45
∠P=45, ∠Q=90

Solve for x. 4 48 X 14<br>can someone solve this for me please? ​
Vikki [24]

Answer:

sure, the answer is 50

Step-by-step explanation: Because this is a right triangle, you can use the pythagorean theorem, which is a^2 + b^2 =c^2 so you square 48 and add it to 14 squared and then take the square roo t to get the value of the hypotenuse, note that c will always represent the hypotenuse or longest side, and that pythagorean theorem can only be used on right triangles

What are all the solutions of x2 + 3x - 4 = 0?<br> 3 ооооооо<br> DONE
Allisa [31]

Answer:

x = -4, x = 1

Step-by-step explanation:

Now I do not know why you said done, but just saying, if you are done with a question, you should delete it. Now I am just going to assume you knew this and move on with the solution of the problem.

When you factor this equation, you will get (x+4)(x-1).

You can then solve for x using zero product property. The first root is -4 and the second root is 1.
