Helppppp im tired and I cant even think no moreee​
Vladimir [108]

Answer:

The equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}

Step-by-step explanation:

We need to find the equation of line, with the given slope passes through the given point.

Slope m = -4

Point: (-2,-9)

We need to find slope and y-intercept of the line.

The slope of line is given m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, we can find y-intercept

The formula used will be: y=mx-b

Putting values of: y= -9, x =-2 and m = -4

y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17

So, y-intercept b = -17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

y=mx+b\\y=-4x-17

Writing equation in required form i.e. of Ax + By = C

y=-4x-17\\4x+y=-17

So, the equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}
