Answer:
x=1, y=2
Step-by-step explanation:
x + 7y = 15
x + 2y = 5
Subtract the two equations
x + 7y = 15
-x - 2y =- 5
------------------------
0x +5y = 10
Divide by 5
5y/5 = 10/5
y =2
Now find x
x+2y = 5
x +2(2) = 5
x +4 = 5
Subtract 4 from each side
x-4+4 = 5-4
x = 1
Answer: C -7/3
Step-by-step explanation: Slope is rise over run, rise/run, and your line means your slope will be negative. So, you will first count straigt down from your firt point until you reach the line of the second point, which is 7. Next, you would count/run to the point, which is 3. Rise/run = -7/3. I hope this helps :)
A. 50 divided by .6 is 30 so .6
B. x=9 y=30
--------------------------
Slope :
--------------------------
Slope = 5/8
--------------------------
Equation:
--------------------------
y = 5/8 x + b
--------------------------
Find y-intercept :
--------------------------
At (8, 2),
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3
--------------------------
Equation :
--------------------------
y = 5/8x - 3
-----------------------------------------------------------------
Answer: y = 5/8 x - 3
-----------------------------------------------------------------
