The line (y=(2p-3)x+6) has slope (13). What will (p) be?

Answer and explanation
Correct answer: \(8\)
In the form \(y=mx+c\), the coefficient of \(x\) is the slope \(m\). Here, the slope is \(2p-3\), so \(2p-3=13\). Hence, \(2p=16\) and \(p=8\). If \(p=7\), the slope would be \(2(7)-3=11\), not 13. Exam tip: To identify the slope, look at the coefficient of \(x\).
