hoa [83]3 years ago
5 0

Answer with Step-by-step explanation:

Assuming the two lines are parallel

Angle ABC= Angle BCD [Being alternate interior angles]

Angle BCD=22

Angle BCD+Angle DCE=180 [Angles in a straight line]

22+ Angle DCE=180

Angle DCE=180-22

Angle DCE= 158

Angle DCE= Angle BCF [ Vertically opposite angles]

Angle DCE=158

Angle ECF= Angle BCD [ Vertically opposite angles]

Angle ECF=22

Find the equation of a line that contains the points (−3,−1) and (−4,−7). Write the equation in slope-intercept form
BARSIC [14]

Answer:

y =6x+17

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (-7- -1)/(-4 - -3)

   = (-7+1)/(-4+3)

   -6/-1

   6

The slope intercept form of the equation is

y = mx+b  where m is the slope and b is the y intercept

y = 6x+b

Substitute a point into the equation

-1 = 6(-3) +b

-1 = -18+b

Add 18 to each side

17 =b

The equation is

y =6x+17
