which equation represents a line with slope of 7 and y - intercept of - 1? a -x + 7y = 1 b 7x + y = - 1 c x…

Explanation:

Step1: Recall slope - intercept form

The slope - intercept form of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y - intercept. Given $m = 7$ and $b=-1$, the equation is $y=7x - 1$.

Step2: Rearrange the equation

Rearrange $y = 7x-1$ to the general form. Subtract $y$ from both sides and add 1 to both sides to get $7x-y = 1$.

Answer:

D. $7x - y=1$
