Answer
The slope is 1.75, and the y-intercept is -3.
Work Step by Step
We know that $y=mx+b$, where m is the slope and b is the y-intercept. Using this, we find that the equation in slope intercept form is:
$$ -4y=12-7x\\ y=-\frac{12-7x}{4} \\ y=1.75x-3$$
The slope is 1.75, and the y-intercept is -3.
