Y - y1 = m(x - x1)
y + 7 = (-1/8)(x - 9)
y + 7 = (-1/8)x + 1.125
Subtract 7 from both sides
y = -1/8x - 5.875
64, 45, 53 I think if I’m wrong don’t be mad haha
Answer:
The bottom one
Step-by-step explanation:
the lowest dot is on -3 so that's the y-intercept
the other is at 2 x and -1 y
2 supplementary angles when added together need to equal 180 degrees.
Add:
3x-23 + 2x-12 = 180
Simplify:
5x -35 = 180
Add 35 to both sides:
5x = 215
Divide both sides by 5:
X = 43
Now replace x with 43 in the equation for angle b:
2(43) -12 = 86-12 = 74 degrees
Angle B = 74 degrees
Answer:
43
Step-by-step explanation:
80-37 = 43
