Considee the linear equation 5x+2y=-20. determine the x-intercept and the y-intercept and use them to graph the line and find the slope of the line.

x-intercept is (-4,0); y-intercept is (0, -10).

Step-by-step explanation:

To find the x-intercept, set y = 0 and solve for x:

5x + 2(0) = -20.  Then 5x = -20, or x = -4.  The x-intercept is (-4,0).

To find the y-intercept, set x = 0 and solve for y:

5(0) + 2y = -20.  Thus, y = -10.  The y-intercept is (0, -10).

Now we have two points on the line, both intercepts.

As we go from (-4,0) to (0, -10), x increases by 4 and y decreases by 10.

Thus, the slope of this line is m = rise / run = -10/4 = -5/2.

The easiest way to graph this line is to plot the two intercepts (-4,0) and (0, - 10) and draw a line through these two points.

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
