What is the equation of this line?
Answer:
D. Y = 4x-6
That is correct. The graph is perfect and you did b correctly
So,
y = mx + b is the slope-intercept form.
"m" represents the slope. It will allow you to find additional points on the specified line by determining the "rise" and the "run." The "rise" means vertical movement, and the "run" means horizontal movement.
"b" represents the y-intercept, which is the point on the line where x = 0. When x = 0, the line crosses, or intercepts, the y-axis.
Hey!
------------------------------------------------
Steps To Solve:
x - 5y = −15 solve for y
~Isolate y by subtracting x to both sides
x - 5y - x = -15 - x
~Simplify
5y = -15 - x
~Divide 5 to each side
5y/5 = -15/5 - x/5
~Simplify
y = -3 - 1/5x
~Put into slope-intercept form
y = -1/5x + 3

Hence, the answer is

Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)
