Write the equation of the line which has a slope of -5 and passes through (-4,4). Write the answer in slope-intercept

y = - 5x - 16

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 5, then

y = - 5x + c ← is the partial equation

To find c substitute (- 4, 4) into the partial equation

4 = 20 + c ⇒ c = 4 - 20 = - 16

y = - 5x - 16 ← equation of line

A

Step-by-step explanation:

The angles ABD and ABF are a linear pair. This means that they are supplementary, as answer A says. Supplementary angles add up to 180 degrees, so to find <ABF you can use 180 - <ABD. Substituted: 180 - 50 = 130 degrees, So <ABF = 130 degrees and the correct answer is A.
