SLOPE OF A LINE Directions : The slope of a line measures the steepness of a graph . To calculate the slope , you must find the
quot of the rise and of the line . The rise measures the vertical change , or change in y - coordinates , between the tw points . The run measures the horizontal change , or change in x - coordinates , between the two points . Find the sle of each line below You can express the stope as a Rise 2 Run simplified fraction , a whole number , or a decimal

Answer:
The value of y is
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem the line passes through the origin
therefore
Is a proportional variation
Find the value of k
with the point
The equation is equal to
so
For
