Hope that helps! I wonder if that's Khan Academy?
Step-by-step explanation:
To answer the question, I assume that the given percentage is in terms of volume. The amount of bleach in gallons is the product of the amount of solution x and the decimal equivalent of the percentage. That would give answer equal to 0.70x. The answer is the second choice.
Y=mx+b is equation form.
Step 1: Calculate slope
Slope= y2-y1/x2-x1
Choose 2 points (8,7) and (0,1)
Apply slope formula: 1-7/0-8=-6/-8=3/4(simplified)
M=Slope
Y=3/4x+B
B=Y intercept: 1
Equation: Y=3/4x+1
(I can give a more thorough explanation if you have any questions).
I need more information, such as, if its a triangle or a square, yk what I mean?
