Answer:
slope = - 3
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 )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
Answer:
f(x)=4x+12
Step-by-step explanation:
it is a because the x-intercept is (3,0), and the y-intercept is (0,-12).
Answer:
Step-by-step explanation:
Look at the top triangle.
It is an isosceles triangle because two of the sides are marked equal.
The angles opposite the congruent sides are called base angles. (in the case x and z)
Base angles of an isosceles triangle are equal.
In addition, we use the Triangle angle sum theorem - the sum of the angles in a triangle is 180 degrees
60 + x + y = 180
x+z =120
but x = z so by substitution
x +x = 120
2x = 120
x = 60
z = 60
likewise for the bottom triangle:
50 +50 + Y = 180
Y = 80
