Score on fourth test should be 95
68 + 79 + 98 + 95 = 340
340 divide by 4 (as there are 4 tests) = 85
Answer:
I would start the graph at (0,36) and go down 12, right 1 until you reach the end of the graph
Step-by-step explanation:
Hope it helps
To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3
Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.
y=3x+b
2=3*(3)+b
2=9+b
-7=b So now we know the y-intercept and slope. We just put them together now
y=3x-7
Answer:
No, a porportional relationship is not shown
Step-by-step explanation:
Up until 4(x) and 10(y), the relationship is porportional. Then, when x increases by 2, y also only increases by 2. Y would need to increase by 5.
