Q. Write the equation of the line that passes through the points (−6,−1) and (8,4). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.Answer:
Calculate slope: Calculate the slopem of the line using the formula m=x2−x1y2−y1 with the given points (−6,−1) and (8,4). m=8−(−6)4−(−1) m=8+64+1 m=145
Choose point: Choose one of the points to use in the point-slope form equation. We will use the point (−6,−1).
Write point-slope equation: Write the equation of the line in point-slope form using the slope m=145 and the point (−6,−1). The point-slope form is y−y1=m(x−x1).y−(−1)=(145)(x−(−6))y+1=(145)(x+6)
Simplify equation: Simplify the equation by distributing the slope on the right side.y+1=145x+145⋅6y+1=145x+1430y+1=145x+715
Subtract 1: Subtract 1 from both sides to get the final point-slope form of the equation.y=145x+715−1y=145x+715−77y=145x+78
