What does it mean if the x-coordinate in an ordered pair is zero? What if the y-coordinate is zero? Both? Explain.
1 answer:
If the x-axis ordered pair is (0,0) and the y-axis ordered pair is (0,0), it is just where the lines intersect or also known as the origin. Both x and y can have a (0) in it.
for example let's say that you have an ordered pair on the X-axis of (5,0) and a ordered pair on the y-axis of (-3,0) it would look like that^^
or if it was just (0,0) it would be a dot in the middle
Don't know if it helped much, but there ya go

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
The formula of a slope:
<em>(x₁; y₁); (x₂; y₂) </em><em>- points on a line</em>
From the table we have
Substitute:
Put the value of a slope and coordinates of the point (1, 0) to the equation of a line:
<em>subtract 2 from both sides</em>
Finally we have:
