Answer: I have no clue but I’ll look into it
Step-by-step explanation:
Im pretty sure it would be 10??? if you are putting it as a subtraction problem if not i would try wording it more clearly
ANSWER: The equation of a line in slope-intercept form looks like the following: y = mx + b
where m is the slope of the line and b is the y-intercept.
Given any 2 points (x1, y1) and (x2, y2) on a line, the slope (m) = (y2-y1)/(x2-x1).
So, Whenever the slope (m) is undefined it means that when you try to
calculate the slope given any 2 points on the line you'll end up with a
zero in the denominator, which is undefined. That is, with an undefined
slope you end up with a vertical line, which has the equation "x=some
number".
m = (y2-y1)/(x2-x1) = (y2-y1)/0 = undefined. This implies that x2=x1. So x is the same for any value of y on the line, which is why the equation is "x=some number" and the line is vertical.
So the equation of a line, in slope-intercept form, with an undefined
slope (m=undefined) crossing through the point (-3, 5) is: x= -3 ,
which is a vertical line.
Hope this helps you
Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4
slope=1/4
y=mx+b
m=slope
b=yint
solve for yint
input a point
(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b
y=1/4x+4
