Step-by-step explanation:
The initial value of the line is always the constant at the end of the equation.
The rate of change is always the coefficient of x.
Answer:
Step-by-step explanation:
1) First, find the slope of the line by using two points on the graph. We can see that (0,5) and (4,0) are clearly marked on the line, so let's use those points. Use the slope formula 
and substitute the x and y values of those points into it, then simplify:
So, the slope is 
.
2) Now, identify the y-intercept on the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that the line intersects the y-axis at (0,5), so that must be the y-intercept.
3) Substitute values for 
and 
in the slope-intercept formula, 
, to write the equation of the line. Since represents the slope, substitute for it. Since represents the y-intercept, substitute 5 in its place. This gives the following answer and equation in slope-intercept form:
on the number line the numbers to the left have least value
Answer:
Ashley’s backpack is the better buy.
Step-by-step explanation:
You have to calculate the price that was paid for each backpack after the discount was applied.
Ashley’s backpack: $65*0.25= $16.25
Final price= $65-$16.25= $48.75
Robbin's backpack: $75*0.3= $22.5
Final price= $75-$22.5= $52.5
According to this, the backpack that is the better buy is the one that Ashley bought because after the discounts were applied it cost $48.75 and Robbin's backpack cost $52.2 which means that Ashley's backpack was cheaper.
