Answer:
y = 4/5x + 3/5
Step-by-step explanation:
In the slope-intercept form, y = mx + b, we need to find the values of the slope (m) and the y-intercept.
Using points (-7, -5) and (3, 3), we can calculate for the slope of the equation given the formula:
Let (x1, y1) = (-7, -5)
and (x2, y2) = (3, 3).
Plug the given values into the slope formula:

Therefore, the slope of the line is 4/5.
Next, we need to find out the value of the y-intercept (b).
We can use one of the given points, (3, 3), along with the slope (4/5) to solve for the y-intercept:
y = mx + b
3 = 4/5(3) + b
3 = 12/5 + b
Subtract 12/5 from both sides:
3 - 12/5 = 12/5 - 12/5 + b
3/5 (or 0.6) = b
Therefore, the y-intercept is 3/5.
We can now establish our linear equation as:
y = 4/5x + 3/5

It can't be a function if our ordered pairs has more than 1 of the same x values. This would create two points on the same line...negating the functions. so, the correct answer would be ... "it is not a function because every y-value has more than one x-value"
namely...(7,11) and (7,3)
Answer:
-6/4 or -3/2
Step-by-step explanation:
Slope is change in y/ change in x
Change in y= -6
Change in x= +4
Answer:
<u>-12x³</u>
(x⁴ +1)⁴
Step-by-step explanation:
y=1/(x^4+1)^3
y= (x⁴+1)-³
<u>dy</u><u> </u>= <u>d</u><u>(</u><u>x⁴</u><u>+</u><u>1</u><u>)</u><u>-</u><u>³</u> × <u>d</u><u>(</u><u>x</u><u>⁴</u><u>+</u><u>1</u><u>)</u>
dx d(x⁴+1) dx
=-3.(x⁴+1)-³-¹× 4x³
= -12x³(x⁴+1)-⁴
= <u>-</u><u>12</u><u>x</u><u>³</u>
(x⁴+1)⁴
