X+y=-1/3
x-y=18
solve the system of equation:
equation 1 + equation 2: 2x=17&2/3=16&5/3
x=8&5/6
y=-1/3 -8&5/6=-8&7/6=-9&1/6
x=
Answer:
y = 2x + 4
Step-by-step explanation:
The question is asking for the equation of the line in slope-intercept form: , where m is the slope and b is the y-intercept.
The y-intercept is where the graph of the line crosses the y=axis, which in this case is at y=4 -- which means that b=4.
We can see that (-2, 0) and (0, 4) are two points on the line. The equation for the slope is , which is (4-0)/(0-(-2)). This is equal to 2. (note: you can think of the slope as rise/run)
Therefore, the equation for the line is y = 2x + 4.

Answer:
The one on the top left should be your answer
Let me know if you got it right!
Answer:
7. <K = <R
8. PR = JK
9. <A = <X
10. TX = AB
For question 7, find the angle that looks the most similar to the angle in the question.
For question 8, since the sides (not the hyp.) are equal, PR will be equal to any of those two.
For question 9, the triangles are positioned differently, but it is the angle with two angle lines on it.
Lastly, for question 10, TX will be the same length as the shortest side in the corresponding triangle.
