Q. The equation for line g can be written as y=103x−8. Perpendicular to line g is line h, which passes through the point (3,−9). What is the equation of line h?Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Determine slope of line g: Determine the slope of line g.The equation of line g is given as y=103x−8. The slope (m) of a line in the slope-intercept form y=mx+b is the coefficient of x. Therefore, the slope of line g is 103.
Find slope of line h: Find the slope of line h. Since line h is perpendicular to line g, its slope will be the negative reciprocal of the slope of line g. The negative reciprocal of 103 is −310.
Use point-slope form: Use the point-slope form to find the equation of line h. Line h passes through the point (3,−9) and has a slope of −310. The point-slope form of a line is y−y1=m(x−x1), where m is the slope and (x1,y1) is a point on the line. Plugging in the values, we get y−(−9)=−310(x−3).
Simplify equation of line h: Simplify the equation of line h.First, distribute the slope on the right side of the equation: y+9=−310(x−3).Next, distribute −310 inside the parentheses: y+9=−310x+10.Then, subtract 9 from both sides to get the equation in slope-intercept form: y=−310x+10−9.Finally, simplify the constant term: y=−310x+1.
