Question

write an equation in slope-intercept form of the line that contains the point (4,5) and is PERPENDICULAR to the line y= (-1/8)x + 17

Answer 1

Answer:

y = 8x - 27

Step-by-step explanation:

→ If perpendicular, negatively reciprocate the gradient

8

→ Write in format

y = 8x + c

→ Substitute in the coordinates

5 = 32 + c

→ Find c

c = -27

→ Write in form

y = 8x - 27
