Answer:
y = -2 when x = 0
Step-by-step explanation:
We are given points on the line such as ( 2, 2) and (6, 10) so we can find the equation of the line then find point (x=0, y=?).
General equation of the line is y = mx +b, where m is the slope and
b is y-intercept (where the line crosses the y-axis)
The slope m = (y2-y1)/ (x2-x1) = (10-2)/(6-2) = 8/4 = 2
Now the equation is y = 2x +b
To find b we substitute any of the points that are on the line, for example
(x=2, y=2) in the equation 2=2*2+b; 2-4 =b; -2 = b
The equation is y=2x -2
If x= 0 then y=2*0 -2; y = -2
Zero because 60 plus negative 60 equals 0
Answer:
1. a=2, b=3 c=4
2.b
3. mean= 29, median=30, all are mode, range=21
Step-by-step explanation:
when you're finding slope with two given point you choose the second point of Y subtract the first point of Y. Second point of X subtract first point of X
slope is the change of Y over the Change of X
(3,9) is the second ordered pair so that will be you x2 and y2 because the point is after (0,3)
equation for slope: y2-y1/x2-x1
what you do is
9-3 = 6
3-0=3
6/3 if you simplify it it is 2.
the slope is 2
plug your numbers into the equation and isolate b which is the y intercept
