The answer is y=1/2x -2

-In order to find this, you need to find the slope first.
-Since the x-intercept is (4,0) and the y-intercept is (0,-2), we can use (y-y1)/(x-x1).
-So, (0 - -2)/(4 - 0) = 2/4 = 1/2 (this is the slope)
-Using y=mx+b, where m= the slope and b=the y-intercept, plug in 1/2 for m and -2 for b
-Now the equation is y=1/2x -2

1. first find the slope from the two points (4,0) and (0,-2)

    the equation is  y2 -y1/ x2 - x1

2. From doing that you will get a slope of 1/2

3. Since we need a y intercept of -2, when you plug in x to the equation the y must equal -2

   the only equation that fits those needs is y = 1/2x - 2

4. You can check by plugging in x as 4(which should give you y = 0), or plug in x as 0(which should give you y = -2

Find the slope given the two points
TEA [102]

Answer:

15. -2  16. 0  17. undefined

Step-by-step explanation:

Slope of two points can be calculated by (y change) / (x change).

(y1 - y2) / (x1 - x2)

15)  (1-5) / (4-2) = -2

16)  (6-6) / (1-10) = 0 since y change is 0.

17) (-5-3) / (4-4) = undefined since x change is 0 but you cannot devide by 0.

What is the solution to the equation One-fourth x minus one-eighth = StartFraction 7 Over 8 EndFraction + one-half x?
snow_tiger [21]

Answer:

The solution to the equation is

x = -4

Step-by-step explanation:

We want to find the solution to the equation

(1/4)x - 1/8 = 7/8 + (1/2)x

First, add -(1/2)x + 1/8 to both sides of the equation.

(1/4)x - 1/8 - (1/2)x + 1/8 = 7/8 + (1/2)x - (1/2)x + 1/8

[1/4 - 1/2]x = 7/8 + 1/8

x(1 - 2)/4 = (7 + 1)/8

-(1/4)x = 8/8

-(1/4)x = 1

Multiply both sides by -4

x = -4
