Identify the y-intercept of the function 7x + 2y = 4.

y-intercept=2

Step-by-step explanation:

To find the y-intercept we need to make x=0.

7(0)+2y=4

2y=4

y=2

So, your answer is 2!

y-intercept is +2

Step-by-step explanation:

To find the y-intercept of the equation we must convert the equation into slope-intercept form to do that we must isolate the variable y.

So,

now we compare it with

y=mx+c

m is the slop which is -7/2 and c is the y-intercept which is +2

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
