Please be clear and point out the exact answers MAT Tbs Spring 2U18 CRN 45236 Online 2417 hi Homework: Section 2.4 Homework Save Score: 0 of 1 pt 4 of 12 (11 complete) X) 2.4.7 Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form. Passing through (2-4) and perpendicular to the line whose equation is y =-x + 4 Write an equation for the line in point-slope form. 5 (Simplify your answer. Use integers or fractions for any numbers in the equation.)Explanation / Answer
point slope form of line is
(y-y1) = m (x-x1)
as line passes through (2,-4)
=> {y-(-4)} = m(x-2)
=> (y+4) = m(x-2) ------------(1)
as line is perpendicular to y = (1/5)x + 4
it means m*(1/5) =-1
=> m =-5
equation (1) gives
(y+4) = -5(x-2) (point-slope form) (answer)
or
y + 4 = -5x +10
=> y = -5x +6 (slope intercept form)
