The two horizontal lines are parallel ( This is given by the red triangles)

Because the lines are parallel, the two angles 1 & 2 would be the same.

Set the two equations for the angle to equal each other and solve:

8y-6 = 7y

Add 6 to each side:

8y = 7y+6

Subtract 7y from each side:

y = 6

Now you have the value for y, solve for angle 2 by replacing y with 6:

Angle 2 = 7y = 7(6) = 42 degrees.

Write an equation of the line that passes through the given points. (-1,5) and (2, - 7)

Vanyuwa [196]

Answer:

The equation of the straight line is 4x +y = 1

Step-by-step explanation:

Step(i):-

Given points are (-1,5) and ( 2,-7)

Slope of the line

$m =\frac{y_{2}-y_{1} }{x_{2} -x_{1} } =\frac{-7-5}{2-(-1)} = \frac{-12}{3} = -4$

slope of the line m = -4

Step(ii):-

The equation of the straight line passing through the point (-1,5) and having slope 'm' = -4

$y - y_{1} = m( x-x_{1} )$

y - 5 = -4 ( x-(-1))

y -5 = -4 x -4

4 x + y -5 +4=0

4x +y -1 =0

Final answer:-

The equation of the straight line is 4x +y = 1
