Question

B.1/3x+y=72x + 6y = 12Questions:•M=slope•Y-intercept•Point intersection

Answer 1

First let's find the slope and y-intercept of each equation by putting them in the form y = mx + b:

`\begin{gathered} (1)/(3)x+y=7 \\ y=-(1)/(3)x+7 \\ \text{slope}\to m=-(1)/(3) \\ y-\text{intercept}\to b=7 \\ \\ 2x+6y=12 \\ x+3y=6 \\ 3y=-x+6 \\ y=-(1)/(3)x+2 \\ \text{slope}\to m=-(1)/(3) \\ y-\text{intercept}\to b=2 \end{gathered}`

Since the lines have the same slope and different y-intercepts, they are parallel lines, therefore these lines have no point of intersection.
