Answer:
k = - 2j + 28
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (14, 0 ) and (x₂, y₂ ) = (0, 28 ) ← 2 points on the line
m = =
= - 2
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
In this graph the y- axis is the k- axis and the x- axis the j- axis , then
k = - 2j + 28 ← equation of line

Draw a diagram (shown below as attachment)
check each option
1st one: obtuse triangle
osbuse means that the triangle has an angle more than 90 degrees
remember that all angles add to 180
90 is one
90+D+F=180
D+F=90
so those 2 mystery angles both have to be less than 90 so therefor none of them can be obtuse
not 1st option
2nd: angle at D is acute
acute means less than 90
so we remember that
D+F=90
no angle can be 0 so let's say F is a very small number like 0.0001
then D would be 89.9999
still less than 90, it is acute
this 2nd optin is right
3rd: angle at F is obtuse
wrong, from 1st one, no obtuse angles
3rd option is wrong
4th: right triangle
duh, a right triangle has a right angle in it
90 degrees is a right angle
yes
4th optin is right
5th: D is obtuse
naw, fam. no obtuse angles here
the right answers are 2nd and 4th or
The angle at vertex D is acute and
Triangle DEF is a right triangle
