So in the question we are given the points: (8,0) and (0,12)
In order to find the slope, we use the equation:
where subscripts 1 and 2 can apply to either of the points as long as they remain consistent. Let's use subscript 1 for the point (8,0) and subscript 2 for the point (0,12):
So now we know the slope of the equation is .
The slope-intercept form of a line follows the form:
where x and y are from a given point on the line, m is the slope of the line, and b is the y-intercept of the line.
So since we are told the y-intercept in the question, we can then plug in the numbers to the equation for the line:
Answer: 5
Step-by-step explanation:
When distributing the negative to the (5-9y) you need to distribute it to both the 5 and the -9 so your 9 should be positive now. So it should be 72+24y = 4y-5+9y
