Slope of 2y = x + 5:-
This is y = 0.5 x + 2.5 in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5
Answer: isosceles
Step-by-step explanation:
By the alternate interior angles theorem,
Since angles in a triangle add to 180 degrees,
Since sides opposite equal angles in a triangle are equal, .
So, triangle ABC is <u>isosceles</u>
The answer is a, it adds one block
