What is the slope-intercept form of the equation y - 7= -5/2(x+4)
1 answer:
The first thing I would probably do is distribute (multiply) the -5/2 into the parenthesis: = (-5/2)x + (-20/2) Notice how I am not putting the x into the fraction. This is to make it easier to see the slope-intercept form. Lets simplify the (-20/2) and then add 7 to both sides: y - 7 = (-5/2)x - 10 y = (-5/2)x - 3 Your answer would then be: y = (-5/2)x - 3 y = mx + b Since it is now in the requested format.

Answer:
Using y = mx + c
slope = -17+5/3-1 = -12/2 = -6
Using point (1 , - 5)
y + 5 = -6(x - 1)
y + 5 = - 6x + 6
y = - 6x + 6 - 5
y = - 6x + 1
Hope this helps.

Step-by-step explanation:
A diameter of the circle.
This is completing the square: (x^2+12x+36)+42-36 Answer: (x+6)^2 +6
To start off, you need to take the cube root of both sides of the equation.
The cube root of 27 is 3, and the cube root of 64 is 4.
The answer would then be x=3/4
