What is the equation helppp

The slope-intercept equation is y=2x+4

Step-by-step explanation:

The y-intercept is where it crosses the y-axis, so 4, and to find the slope find perfect points or pretty points and rise then run.  I took the point (0,4) and found the next pretty point (1,6) and rise/run it. In order to get to the next point  you have to rise 2 and run 1 or 2/1 which is 2, so the slope is 2, then you plug it into the equation y=mx+b the y=intercept is b and the slope is m.  

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
