The total number of DVDs that she bough is 6
<h3>Linear equations</h3>
Linear equation are expression that has a leading degree of 1.
Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each and spent a total of $363.50, ten;
329 + 5.75x = 363.5
Subtract 329 from both sides
329 + 5.75x - 329 = 363.5 - 329
5.75x = 34.5
x = 34.5/5.75
x = 6
This shows that the total number of DVDs that she bough is 6

Answer:
The equation of the line is y=1.4x+6.8
Step-by-step explanation:
Given 2 points on the graph, you can find the slope using the equation: 
. The 2 points are (-7, -3) and (-2, 4). X1 is -7, X2 is -2, Y1 is -3, Y2 is 4. The slope would be 1.4 once you plug in the numbers to the equation to finding the slope. Once you find the slope, use one of the points to find the y-intercept along with the slope you found and the y-intercept will be 6.8.
