Concept:The slope of a line can be found by rewriting its equation in the form y=mx+c, where m is the gradient.Explanation:Start with the given equation:3x−5y=7Rearrange it to make y the subject.First, move 3x to the right side:−5y=−3x+7Divide both sides by −5:y=−5−3x+7Simplify:y=53x−57Now compare with y=mx+c.The coefficient of x is the gradient:m=53Answer:The gradient is 53, which is option B.
