 Question 55930: Find an equation in slope-intercept form passing through the points (-6.2, 18.1) and (3.4, 18.1) ...any help here would be appreciated!Answer by Lacey020991(49)   (Show Source): You can put this solution on YOUR website!The slope-intercept formula is y=mx+b . First you have to find your slope The slope, m, of the line is the change in y divided by the change in x. . m = (y2-y1) / (x2-x1) x1= -6.2 ; y1= 18.1 x2= 3.4 ; y2= 18.1 . m= (18.1-18.1) / (3.4- -6.2) m= 0 / 9.6 m= 0 . If your slope would have 9.6 / 0 the slope would have been undefined and it would have been a vertical line, but since it's a slope of zero it's going to be a horizontal line. . Now, to find the y-intercept, b, use one of the points to get the x and y values, and solve for b. . y1 = mx1 + b b = y1 - mx1 . b = 18.1 - 0(-6.2) b = 18.1 So your equation is : y = 18.1 . Your graph will just be a horizontal line at 18.1.
