Which equation represents a line with slope 2 and y-intercept -3?किस समीकरण वाली रेखा की ढाल 2 और y-अवरोध -3 है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(y=2x-3\)\(y=2x-3\)
The slope-intercept form is \(y=mx+c\), where \(m\) is the slope and \(c\) is the y-intercept. With \(m=2\) and \(c=-3\), the equation is \(y=2x-3\). Option B has a negative slope. Exam tip: the coefficient of \(x\) gives the slope.रेखा का ढाल-अवरोध रूप \(y=mx+c\) होता है, जहाँ \(m\) ढाल और \(c\) y-अवरोध है। यहाँ \(m=2\), \(c=-3\), इसलिए \(y=2x-3\)। विकल्प B की ढाल ऋणात्मक है। परीक्षा टिप: \(x\) का गुणांक ढाल बताता है।
