Find an equation in slope-intercept form of the line that has slope 2 and passes through point A(-8, 7).
a. y = 23x + 2
c. y = 2x - 23
b. y=-2x+23
d. y = 2x + 23

y = 2x+23

Step-by-step explanation:

The slope intercept form is

y= mx+b

where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation

7 = 2(-8) +b

7 = -16+b

Add 16 to each side

7+16 = -16+b+16

23 =b

The equation becomes

y = 2x+23

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
