Answer:
y=6x-2
Step-by-step explanation:
Fisrt things first, you want to find the slop. One of the points is (1,4). You want the other point. Using the y-int, you can figure out the other point is (0,-2). You get this because the y-intercept means the x value is 0.
Next you use the two points and plug it into the formula (change in y/ change in x)
(-2-4)/(0-1)=-6/-1 = 6
Now you know the slope is 6. Since you know the y-int, you can plug that into the slope-intercept formula (y=mx+b)
That would give you: y=6x-2
The answer as a decimal is -42.6
Answer:
y-intercept: (0, 5); slope: 1/4
Step-by-step explanation:
The slope (m) is found from ...
m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, this is ...
m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C
__
Then, the point-slope form of the equation of the line can be written as ...
y -y1 = m(x -x1)
y -6 = (1/4)(x -4) . . . fill in known values
y = 1/4x -1 +6 . . . . . add 6
y = 1/4x +5
Then the value of y when x=0 is ...
y = 0 +5 = 5
So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
