Write the equation in slope intercept form. what are the slope and y-intercept?
-3x - 10y = 7

slope intercept is basically solve for y

y=mx+b

m=slope

b=yintercept

-3x-10y=7

add 3x to both sides

-10y=3x+7

divide both sides by -10

y=-3/10x-7/10

slope is -3/10

yintercept is -7/10 or at point (0,-7/10)
