Step-by-step explanation: x= 2-y then plug that in for x so y= 2-y+2;
y=4-y; -4y=-y; y=-1/4
Answer:i dont not
Step-by-step explanation:
Answer:
y = 8/5x + (-4) or y = 8/5x -4
Step-by-step explanation:
Slope-intercept form is written like this:
y = mx + b
The variable <em>m</em>, represents slope and <em>b</em>, represents the y-intercept.
To find slope, you have to find the rise/run or in other words, change of y over change of x.
From the look of the line, the slope has to be positive because the line is going up.
To go from the bottom point to the top, we have to go up 8 points and go to the right 5 points. Thus the slope is 8/5.
Now for the y-intercept. This part is easy. Just ask yourself this...
"Which of the two points is on the y-axis?"
In this case, it is the bottom point which is -4.
So your equation should look like this:
y = 8/5x + (-4)
or y = 8/5x - 4 because when you have a plus sign and a minus sign, the result is negative.
hope this helps :)
Subtract 5x and add 3y from the left side so that it can be moved to the right side. This will allow you to solve and get the second equation.
