Write an equation for the line that connects A (-4,8) and B (6,3)

Mazyrski [523]

Answer:

7y+5x=76

Step-by-step explan

A (-4,8) and B (6,3)

First find the slope;

m= (y2-y1)/(x2-x1)

m=(3-8)/(3+4)

m=-5/7

now using equation of line

y-y1= m(x-x1)

y-8=-5/7 (x+4)

y-8=(-5x+20)/7

7(y-8)= -5x+20

7y-56=-5x+20

7y+5x=20+56

7y+5x=76

If a is a rational number and b is a rational number, then the product ab must be

alukav5142 [94]

The best way to answer this is to find counterarguments for each answer to eliminate them as a possibility. ab doesn't have to be an integer, 2.5*3=7.5 . That's also not an imaginary number so that's out. And that's also not an irrational number so that's out too. Only choice left is rational number.
