Answer: y= -3x + 4
Explanation: As the general equation of line is y= mx + c where m is the slope of the line and c is the y intercept.
=> for m we need to find the slope of line which is y2 - y1/ x2 - x1
=> 7-1/ -1-1 = 6/-2 = -3
and as we can in the diagram the y intercept is 4
that means our equation for the given line is y = -3x + 4.

Angles of xyz are in the ratio 3:3:6. What are the measures of the angles
tankabanditka [31]
Let
x = 3a (first angle)
y = 3a (second angle)
z = 6a (third angle)

The total angle of a triangle is ALWAYS 180.
3a + 3a + 6a = 180
12a = 180
a = 15

Therefore, x = 45, y = 45, z = 90
