Answer:
y=b slope= 4/1
Step-by-step explanation:
In this question, you are given the average speed of the car(70miles per hour) and the time of car travel(4.5 hours). The information is enough to find the car travelling distance. The equation would be:
Distance traveled= average speed * duration= 70miles/h * 4.5 h= 315miles
Answer:
2b
Step-by-step explanation:
First you need to find the slope of the line. So what you need to do is y^2-y^1 / x^2-x^1
(x^1, y^1) (x^2, y^2)
( -1, 7) ( 2, 10)
10-7/ 2- (-1)
3/3=1
slope is 1
I got 8 as the y intercept. Reason how is that I made a table. And what I did was go back instead of going forward.
x y
-1 7
0 8
1 9
2 10
The answer would be x= 1 y= x + 8 y=8 But the answer choice you listed for A. would not match up the 2 coordinate you gave. Make sure a. should be x= 1 y= x + 8 y=8, not -x y= 8-x y=8
Step-by-step explanation:
the second one, of course.
a y-intercept is a point where x = 0.
the 2 options are clearly having y-values of -2 and +2.
