What is the slope of the line through (6,9) and (7,1)

-8

Step-by-step explanation:

The slope, given two points, is found by

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

    = (1-9)/(7-6)

    = -8/1

   = -8

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
