Answer:
y = -3, slope = 0
Step-by-step explanation:
1) First, find the slope of the line. Substitute the x and y values of the given points into the slope formula, , and solve:
Thus, the slope is 0.
2) If a line has a slope of 0, that means it is horizontal. All horizontal lines are represented by the equation y = a number. That number is determined by the y-value of all the points the line intersects. Thus, find the y-value of the given points and put it into the equation. Looking at the given points, that number would be -3, so y = -3 is the equation.
