Answer:
Step-by-step explanation:
4x+5y = 15
slope of line is -⅘
perpendicular to the line is 5/4
point-slope equation for line of slope 5/4 through (-4,-1):
y+1 = (5/4)(x+4)
Answer:
x = -2
Step-by-step explanation:
Distribute: 18x + 24 = 4x - 4
Subtract 4x from both sides: 14x + 24 = -4
Subtract 24 from both sides: 14x = -28
Divide both sides by 14: x = -2
Answer: 1.8 for the radius
