Answer:

1.  y = x + 7

Step-by-step explanation:

Find the slope

Choose two points and find the slope using rise/run

(1,8) (2,9)

9-8/2-1

1/1 = 1 = m (slope)

Find b using the slope and one point

m=1   (1,8)

8 = 1 (1) + b

8 = 1 + b

7 = b

Fill in m and b into y = mx + b

y = 1x + 7

What slope does a horizontal line have? Use a number to fill in the blank. HELP FOR TESTTTTTT
Alex73 [517]

Answer:

The slope of a horizontal line is zero

Step-by-step explanation:

All horizontal lines are parallel to the x-axis.

The x-axis has a zero slope.

All parallel lines have the same slope.

Therefore the slope of a horizontal line is zero.

This means there is no rise in y.

So rise over run will become:

0/run=0

Answer:

  • The graph has a minimum.
  • The graph has a y-intercept at (0, -3).
  • The solutions ... are -1 and 3.
  • The vertex is located at (1, -4).
  • In the equation, 'a' would be positive.

Step-by-step explanation:

When the graph has a low point, it has a minimum. 'a' is positive in that case. The coordinates of that low point are (1, -4). That point is the vertex.

The graph crosses the y-axis at y = -3, so the y-intercept is (0, -3).

The graph crosses the x-axis at (-1, 0) and (3, 0). These points represent the solution to the equation y = 0.

  • The graph has a minimum.
  • The graph has a y-intercept at (0, -3).
  • The solutions ... are -1 and 3.
  • The vertex is located at (1, -4).
  • In the equation, 'a' would be positive.
