The change in 𝑦 divided by ÷ the change in 𝑥 always gives the gradient as \(\frac{-1}{2}\). The line crosses the 𝑦-axis at 3, so the 𝑦-intercept is 3. Back to top Equation of a line ...

However, conventional sintering technologies face significant challenges in enhancing the voltage gradient without compromising other performances. The high sintering temperature (typically ~1200 ...
