Question

What is the y-intercept of the line 5y - 7x = 25?

Answer 1

Answer:

You need to get the equation down to y = mx + b where m is the slope.

Put 7x on the left hand side. 7x + 25 = 5y

Divide by 5 7x/5 + 25 = 5y

1.4x + 5 = y

the slope is whatever is in front of the x.

Slope = 1.4 <<<<< answer

Your instructor may want it as an improper fraction

7/5 = slope <<<<< answer

Answer 2

Answer:

The y-intercept of the line 5y-7x=25 is 5.

Step-by-step explanation:

Equation of a straight line drawn on a cartesian coordinate system is $y=mx+c$

Here $y$ is vertical axis and $x$ is the horizontal axis.

$m$ is the slope

$c$ is the y-intercept, that is where the line cross the y-axis.

The x and y intercepts and the slope are called the line properties.

The y-intercept formula says that the y-intercept of a function y=f(x) is obtained by substituting x=0 in it.

Now the given line is

$5y-7x=25\\5y=7x+25$

y-intercept means x=0

$5y=25\\y=5$
