Answer:

1 and 7

Step-by-step explanation:

The slope is the number before x. It is identified as m.

Since we know that any variable by itself, without a coefficient, means that there's a 1 in front of it, we can say that 1 is the slope because there's no coefficient shown.

The y-intercept is the number added or subtracted after the slope and x.

Since we have +7 coming after x, we can say that the y-intercept is 7.

Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So remember that perpendicular lines have slopes that are negative reciprocals to each other and parallel lines have the same slope. To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

$\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}$
