Write an equation for a line with a slope of -2, and a y-intercept of 1.

y = -2x + 1

Step-by-step explanation:

Use slope intercept form, y = mx + b, where m is the slope and b is the y intercept:

Plug in the slope and y intercept:

y = mx + b

y = -2x + 1

So, the equation of the line is y = -2x + 1

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

i believe that the answer is

b. y-1=-2(x-4)

hope this !
