A line passes through the point (-8,7) and has a

zaharov [31]

Answer:

y = (-5/2)x + 27

Step-by-step explanation:

Use the point slope formula y = mx + b.

Replace m with -5/2, x with -8 and y with 7:

7 = (-5/2)(8) + b. Find the y-intercept, b:

7 = -20 = b, or b = 27

The equation of this line is y = (-5/2)x + 27.

Y = 90 degrees

1) The angles on a straight line add to 180 degrees so 180-110= 70 degrees.

2) The angles in a triangle add to 180 degrees so 70+70= 140 degrees. The angle at the top of the triangle will have to be 40 degrees as 140+40= 180 degrees.

3) As x is half the angle at the top of the triangle (40 degrees), x will equal 20 degrees.

4) As the angles in a triangle add to 180 degrees 20+70=90 degrees 180-90=90 degrees.

5) Answer = 90 degrees
