Which equation represents a line that passes through (–9, –3) and has a slope of –6?
Fiesta28 [93]
Using slope-intercept form, y = mx + b where m = slope and b = y-intercept:

We know our slope is -6. This can be interpreted as -6/1, which rise-over-run-wise, means that when y changes by 6, x changes inversely by 1.
To find that y-intercept, though, we need to find the value of y when x = 0.
Use our point (-9, -3) to find this...
We want to add 9 to x so that it becomes 0.
According to our slope, this means subtracting 54 from y.
Our y-intercept is at (0, -57), with -57 being the value of b we put in our equation.

\boxed{y=-6x-57}

You could also just use point-slope form:
y - y¹ = m(x - x¹)
y - (-3) = -6(x - (-9))
y + 3 = -6(x + 9)
And convert to slope-intercept if you want:
y + 3 = -6x - 54
y = -6x - 57

Rashid [163]

Answer:

1/8

Step-by-step explanation:

1/6 × 3/4

Multiply across top, then bottom

1×3=3

6×4=24

Then reduce if necessary.

3/24

Divide top and bottom by 3

3÷3=1

24÷3=8

You should get 1/8
