slope intercept form is y=mx+b
so solve for y
2x+y=-3
minus 2x both sides
y=-2x-3
-2y=6+4x
divide both sides by -2
y=-3-2x
y=-2x-3
Try to use the total which is 650 - 247
by that will give you the answer
There are always 180° in a triangle, so to work out the missing angle, you add up the angles you have and do 180 - that answer.
So it would be:
79 + 37 = 116
180 - 116 = 64.
y = 64 :)
