To find AB(x) and BC(y), you can do(there are multiple ways you can do this):
tan A =
tan 60° = or (tan 60°) · 7 = y
tan 60° =
√3 · 7 = y
7√3 cm = y
sin B =
sin 30° = or
sin 30° = =
x =
x = 14 cm
AB = 14cm
BC = 7√3 cm
Option C
<u> Answer: </u>
The equation in slope intercept form is
The slope is and y-intercept is
<u>Solution: </u>
The slope - intercept form equation of line is given as
y = mx + c ---- eqn(1)
Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.
c is the y – intercept which is the value of y at the point where the line crosses the y-axis
From question, given that -5x - 12y = 11 --- eqn (2)
On converting equation (2) in slope – intercept form, that is adding 5x on both sides,
-5x - 12y + 5x = 5x + 11
-12y = 5x + 11
Now on dividing -12 on both sides,
---- eqn (3)
Comparing the given equation (3) with equation (1), we get
and
Hence Option C is correct.
