Answer:   (0, 3)

<u>Step-by-step explanation:</u>

The y-intercept is where the line intercepts (crosses) the y-axis (up/down axis).


The line crosses the y-axis at 3.  <em>When x = 0, y = 3</em>

The y intercept is 3

You can also say that the y intercept is at (0,3) which is a more detailed answer. However saying "y intercept is 3" is sufficient enough because the x coordinate of the y intercept is always x = 0.

The y intercept is the location where the graph crosses or touches the y axis. This is at the halfway point between the 2 and 4, so (2+4)/2 = 6/2 = 3

madam [21]

Answer:

x = 1.5

Step-by-step explanation:

Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.

(-7 + 10) / 2

3/2

= 1.5

So, the axis of symmetry is at x = 1.5

Are the two figures below similar? If so, how do you know?
artcher [175]
No because the scale factor is inconsistent while it would be neccecary to be consistent if it was similar. 19.9/15.3=1.3 while 29/25=1.16 which proves that they have an inconsistent scale factor.

You can set this up as a system of equations.

x + y = 19
10x + 25y = 3.70

Your answer would be 31.42 dimes and -12.42 quarters.
