What is the equation of a line that passes through the points (-3,4) and (2, 8
1 answer:
Answer:
y = 4/5x + 32/5
Step-by-step explanation:
(-3,4) and (2, 8)
Slope:
m=(y2-y1)/(x2-x1)
m=(8-4)/(2+3)
m= 4/5
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = 4/5(x + 3)
y - 4 = 4/5x + 12/5
y = 4/5x + 32/5

Answer:
Step-by-step explanation:
y=-5x-13
Since we know the value of y we can substitute it in
6x+6(-5x-13)=-6
6x-30x-78=-6
-24x=72
-x=3
x=-3
Now that we know the value of x we can solve Y
y=-5(-3)-13
y=15-13
y=2
2x = 8 - 5y
x = 8/2 - 5y/2
x = 4 - 2.5 y
or
x = 4 - 5/2 y
<12 would be A (51 degrees) because 2 and 10 are corresponding angles and there are 180 degrees on a straight line!
Hope this helps :)
