Q. Complete the equation of the line through (−8,−2) and (−4,6). Use exact numbers.y=□
Finding the Slope: To find the equation of a line, we need to determine the slope (m) and the y-intercept (b) of the line. The slope can be found using the formula m=x2−x1y2−y1, where (x1,y1) and (x2,y2) are the coordinates of the two points the line passes through.Let's calculate the slope using the points (−8,−2) and (−4,6).m=−4−(−8)6−(−2)m=−4+86+2m=48b0
Using Point-Slope Form: Now that we have the slope, we can use point-slope form to write the equation of the line. The point-slope form is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line.Let's use the point (−8,−2) and the slope m=2 to write the equation.y−(−2)=2(x−(−8))y+2=2(x+8)y+2=2x+16
Converting to Slope-Intercept Form: To write the equation in slope-intercept formy=mx+b, we need to isolate y on one side of the equation.Subtract 2 from both sides to get y by itself.y=2x+16−2y=2x+14
