Question

A line has a slope of negative 2 and passes through the point begin ordered pair 4

comma negative 9 end ordered pair-
Which equation is the equation of the line?

y equals negative 2 x plus 1
y equals negative 2 x minus 1
y equals negative 2 x plus 17
y equals negative 2 x minus 17

Answer 1

Answer: y equals negative 2 x minus 1

Explanation:

The way to solve this is plug in the slope then find the difference of the result and the y value:

y = -2x

y = -2(4)

y = -8 SO

-8 + ? = -9

? = -1

That is the y intercept.

y = -2x - 1

The answer is y equals negative 2 x minus 1.
