Find the slope and y-intercept of each linear equation 30 points

Mathematics
1 answer:
uranmaximum [27]3 years ago
6 0

Step-by-step explanation:

<u>The slope-intercept form:</u>

  • y = mx + b, where m- slope, b- y-intercept

<u>Given lines:</u>

1)

  • y = - 2x + 7
  • m = - 2, b = 7

2)

  • y = 6x + 11
  • m = 6, b = 11

3)

  • y = -2.5x + 3.2
  • m = - 2.5, b = 3.2

4)

  • y = 1/4x - 2/7
  • m = 1/4, b = - 2/7

There are 2 more angles. m angle 7 and m angle 8
Licemer1 [7]
ANSWER:

A and B aren't parallel lines, as the alternate angles aren't equivalent to each other.

For m angle 1 -

Vertically opposite angles are equivalent to each other.

m angle 1 is vertically opposite m angle 4.

Therefore:

m angle 4 = 100

m angle 1 = m angle 4

m angle 1 = 100

For m angle 6 -

Co-interior angles add up to 180°.

m angle 4 and m angle 6 are co-interior angles.

Therefore:

m angle 4 = 100

m angle 4 + m angle 6 = 180

100 + m angle 6 = 180

m angle 6 = 180 - 100

m angle 6 = 80

For m angle 7 -

Vertically opposite angles are equivalent to each other.

m angle 6 is vertically opposite m angle 7.

Therefore:

m angle 6 = 80

m angle 7 = m angle 6

m angle 7 = 80

For m angle 8 -

Corresponding angles are equivalent to each other.

m angle 8 and m angle 4 are corresponding angles.

Therefore:

m angle 4 = 100

m angle 8 = m angle 4

m angle 8 = 100

Hence, the angles are as follows:

m angle 1 = 100

m angle 6 = 80

m angle 7 = 80

m angle 8 = 100
