Answer:
-28/3
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
15-(-13)/-12-(-9)
28/-3 or -9 1/3
Best of Luck!
If a decimal repeats, that means it can be written over 9. So 0.7 repeating equals 7/9. Then add the amount to the left of the decimal, in this case 3. 3 + 7/9 = 3 7/9
Hi Mark
3x+y=4
2x+y=5
Solve 3x+y=4 for y
Add -3x to both sides
3x+y-3x=4-3x
y=-3x+4
Substitute -3x+4 for y in 2x+y=5
2x+y=5
2x-3x+4=5
Simplify both sides of the equation
-x+4=5
Add -4 to both sides
-x+4-4=5-4
-x=1
Divide both sides by -1
-x/-1= 1/-1
x=-1
Substitute -1 for x in y=-3x+4
y=-3x+4
y=(-3)(-1)+4
Simplify both sides of the equation
y=7
Answer: (-1,7)
