$21.60 - $18.00 = $3.60
$3.60 : $18.00 = 0.2
0.2 · 100% = 20%
The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
What is the slope-intercept form of a line?
The conventional form Ax + By = C and y= mx + b have been used to describe linear equations. The slope-intercept form y = mx + b will now be the focus of our attention.
You can write a linear function using the slope of the line and the y-intercept in the slope-intercept form.
y=mx+b
Where b is the y-intercept and m is the slope.
A straight line's slope-intercept equation is written as y=mx+b, where m denotes the slope and b is the y-intercept.
In this case, m=3 and b=5 and y=3x+5 y=3x+5 is the necessary equation.
Hence,The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
