 Question 398057: Answer by lwsshak3(6513)   (Show Source): You can put this solution on YOUR website!Find an equation in slope- intercept form passing through the points (-6.2,18.1) and (-3.4,18.1). The slope-intercept form is y=mx+b, with m=slope and b=y-intercept slope by definition is a change in y divided by a change in x, also called rise/run. Note there is no change in y from the points given, so the slope is zero. So the x goes away in the above equation, leaving y=b or y=18.1 in this case. Based on the points given, this is a horizontal line 18.1 units above the x-axis for all real values of x. ans: equation of this line is y=18.1
