Question

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

Answer 1

Answer:

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!

Answer 2

Answer:

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,

$7x+2y=4\\2y+7x=4\\2y=-7x+4\\y=\frac{-7x+4}{2} \\y=\frac{-7x}{2}+\frac{4}{2} \\\\y=\frac{-7x}{2}+2$

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
