Write the equation of a line whose slope is 2/3 and crosses the y axis at (0, -5)

Answers

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

$y=(2)/(3)x-5$

Step-by-step explanation:

We will use the slope intercept form of the equation to make an equation of the given line

The slope-intercept form is:

$y=mx+b$

Here m is the slope and b is the y-intercept

Given

m = 2/3

Putting the value of slope

$y=(2)/(3)x+b$

The y intercept is -5 so we will put in the equation

$y=(2)/(3)x-5$

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

$y=(2)/(3)x-5$

Kevin has in a savings account = $1,427

His brother Haley has saved in the month with a 4 that is 1/10 the value of the 4.
