Chapter 3 - Graphing Linear Functions - 3.5 - Graphing Linear Equations in Slope-Intercept Form - Exercises - Page 142: 22

Answer

The slope is $7$, and the $y-$ intercept is $\frac{1}{2}$.

Work Step by Step

The given equation is $\Rightarrow 0=1-2y+14x$ Add $2y$ to each side. $\Rightarrow 0+2y=1-2y+14x+2y$ Simplify. $\Rightarrow 2y=14x+1$ Divide each side by $2$. $\Rightarrow \frac{2y}{2}=\frac{14x+1}{2}$ Simplify. $\Rightarrow y=7x+\frac{1}{2}$ The slope-intercept form is $\Rightarrow y=mx+b$ $y-$intercept is $b=\frac{1}{2}$. The slope is $m=7$ Hence, the slope is $7$, and the $y-$ intercept is $\frac{1}{2}$.
