Answer:
y = 2/5x
Step-by-step explanation:
Perpendicular lines are lines which have negative reciprocal slopes of each other.
The line y = -5/2 x + 2 has slope -5/2. Therefore its perpendicular slope will be 2/5.
The equation can cross anywhere on the y-axis for its y-intercept since no specific point is given. Here I chose (0,0).
y = 2/5x
Answer:
Check explanation.
Step-by-step explanation:
slope-intercept form: y=mx+b
9x+5y=23
5y=-9x+23
y=-9/5x+23/5
m=slope: -9/5
b=y-intercept: 23/5
