I need some help with these slope questions.

Step-by-step explanation:

6.

if the slope is 8 , y-intercept is 2

use the general equation for slope intercept y= mx+b where m is slope and b is y-intercept

y= 8x +2

7.

slope is 0, y- intercept  is -3

y= 0*x -3  the equation is y= -3

8. (same steps for 9)

slope is 5, and (2,7) on the line

use the point slope equation (y-y1) = m( x-x1)

y-7 = 5 (x-2)

now transform it into the slope intercept form y= mx+b

y = 5x - 10 + 7; y = 5x -3

5.

between the points (0, -2) and ( 2, 0 ) the slope is m = (y2-y1)/(x2-x1) =(-2-0)/(0-2) = 1, and the y-intercept is -2

y= 1*x -2 ; y=x-2

13.

a. y= 18x +10 because the distance y is 18 for each x hour plus the extra 10 miles that she had at the start

b. the y-intercept is where the graph intersects the y-axis so is 10 and represents the starting point at 10 miles , and the slope is 18 and represents how fast is moving

c. after 2 hours means x=2

y= 18*2 +10 = 36+10 = 46 miles

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

not sure but it may be b, as i said i'm not sure.
