The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...

Watch this video to find out how to determine if a straight line graph ... This gives the 𝑦-intercept as 𝑐 = –1. Write the equation of the line in the form 𝑦 = m𝑥 + c.
