Change the line 3x − 8y = 5 into slope-intercept form.

m=slope
b=y intercept

solve for y basically


3x-8y=5
minus 3x both sides
-8y=-3x+5
divide both sides by -8
y=\frac{3}{8}x-\frac{5}{8}

notka56 [123]

Answer:

Javier rode bike 34 minutes before lunch.


Step-by-step explanation:

Total number of minutes he rode bike = 41 min

Therefore,

x+5x-1 =41


On solving

Divide both side by 6 we get

x= 7


Number of minutes he ride before lunch

= 5(7)-1 = 35-1=34 min
