Find the value of x L 7x-7 M 4x+14
viktelen [127]

Answer:

x= 7 sorry if I'm wrong:(

Step-by-step explanation:

Which equation has a slope of -2 and passes through the point (1,-6)?
Naily [24]

Answer:

y=-2x-4

Step-by-step explanation:

Given that,

Slope, m = -2

It passes through the point (1,-6).

We need to find the equation of line that passes throgh the given point. It can be calculated as:

y-y_1=m(x-x_1)

Put y₁ = -6, x₁ = 1 and m = -2

y-(-6)=(-2)(x-1)\\\\y+6=-2x+2\\\\y+2x+6-2=0\\\\y=-2x-4

Hence, the equation of line is y=-2x-4.
