Do you know what slope intercept form is?
y = mx + b
m being the slope
b being the y-intercept
So all you have to do is isolate y to get:
5y = -4x + 10
y= -4/5x + 2
We can see the slope is -4/5 and the function intercepts the y axis when at y = +2
To graph the function, start at the y-intercept since we know where it is. That’s (0,2). Now the slope says down 4 and right 5. Or you could do up 4 and left 5
25% is equal to 1/4, so if 300 is 1/4 and we need to find the total, then we should divide 300 by 4.
300 • 4 = 1200, thus 25% of 1200 is 300!
Hope this helps.
The answer to the question
5 - X - X = -1
5 - 2x = -1
-2x = -1 - 5
-2x = -6
X = 3.
