Answer:
The value of slope m = -1
Step-by-step explanation:
x = -2 + 4t
and y = 1 + 4t
Solving the both equations
x +2 = 4t
=> t = (x+2)/4 eq(1)
y-1 = 4t
=> t = (y-1)/4 eq(2)
Putting eq(1) = eq(2) as left hand side of both equations are same
(x+2)/4 = (y-1)/4
Cross multiplying
4(x+2) = 4(y-1)
4x + 8 = 4y -4
4x +4y = -4 -8
4x + 4y = -12
4(x+y) = -12
x+y = -12/4
x+y = -3
y = -x -3
The slope intercept form of line is:
y = mx + b
where m is the slope. Comparing with y = -x-3
The value of slope m = -1
Answer:
Step-by-step explanation:
The best estimate for 1,374 is 1,400 and the best estimate for 6 is 10. This is because anything that is 5 and above you change it. Example: 16 the best estimate for 16 is 20 because 6 is above 5. And when a number is 4 and below you change the number below. Example: 12 the best estimate for 12 is 10 because 2 is below 4. And when the number is perfect like 10, you can keep the number the same. Example:10,20,30,40,50,60etc.
Hope this Helped! :)
The correct answer is y = 11
because:
2y + 7 = 3y − 4
−y + 7 =−4
Subtract 7 from both sides.
−y + 7 − 7 = − 4 − 7
−y = −11
Divide both sides by -1.
y = 11
