Linear equations can be written in the form y = mx + b where the multiplier, m, or the coefficient of the x-term represents the slope of the line and the b represents the constant term or the y-intercept.
So we can write an equation in y = mx + b form by first noticing that our slope is equal to -7 and our constant term is equal to 12.
So our linear equation can be written as y = -7x + 12.
