Answer:

y = -1/2 x - 5

Step-by-step explanation:

y = mx + b

m = slope = -1/2

y = -1/2 x + b

-7 = -1/2 * 4 + b

-7 = -2 + b

b = -5

y = -1/2 x - 5

Step-by-step explanation:

y = -0.5x + c

When x = 4, y = -7.

=> (-7) = -0.5(4) + c, c = -5.

Therefore the equation is y = -0.5x - 5.

What is the slope of this line? (-4.5) (0.6) (8.8) Enter your answer in the box.
Luden [163]

Answer:

m= 1/4

Step-by-step explanation:

1) Take two points. Let's use the first and second. Subtract one y coordinate from the other. 6 - 5 = 1

2) Do the same process with the x coordinates. 0 - -4 = 4 (0 + 4)

3) Make the answer from the y coordinates the numerator and the answer from the x coordinates the denominator, and you have your final answer: 1/4
