Write the standard form of each equation.
0=-x+y+3

y = x - 3

Step-by-step explanation:

Linear equations are most often written in the form y = mx + b, where m is the slope of the line.

Here, 0=-x+y+3 can be re-written as x - 3 = y, or y = x - 3.  Here the slope is 1 and the y-intercept is (0, -3).

54.864 meters

step-by-step explanation:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
