Find the Slope:
AveGali [126]

Answer:

4) slope= 0

5) slope =  -  \frac{1}{7}

Step-by-step explanation:

\boxed{ slope = \frac{y _{2} - y_1 }{x_2 - x_1} }

4) Slope

=  \frac{10 - 10}{ - 10 - 3}

=  \frac{0}{ - 13}

= 0

The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).

5) Slope

=  \frac{5 - 4}{2 - 9}

=  \frac{1}{ - 7}

=  -  \frac{1}{7}

Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.

Find the x and y intercept for -2x-5y=30
Ahat [919]

Answer:

see below

Step-by-step explanation:

-2x-5y=30

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

-2x-5*0=30

-2x = 30

Divide each side by -2

-2x/-2 = 30/-2

x =-15

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

-2*0-5y=30

-5y = 30

Divide each side by -5

-5y/-5 = 30/-5

y = -6
