So 1 would be 5r+20 and then the second one would be
Answer: 2
(The slope is always the coefficient of the independent variable, in this case x . The slope is therefore 2.)
4) The ratio of lemons to cups of sugar = 2/3 or 2:3
5) The ratio of cups of sugar to cups of water = 3/14 or 3:14
Hope that helps
Answer:
5/3 or 1.67
Step-by-step explanation:
Find the slope of the original line
3x+5y=4 Subtract 3x from both sides
5y = - 3x + 4 Divide both sides by 5
y = (-3/5)x + 4
The original line has a slope of - 3/5 or - 0.6
Find the slope of the perpendicular line
m1 * m2 = - 1
m1 = - 3/5
m2 = -1/(-3/5)
m2 = 5/3
The slope of the perpendicular line is
5/3 or 1.67
