Answer:
The equation of the line is -x + 4y = -8
Step-by-step explanation:
To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (1 - -3)/(12 - -4)
m = (1 + 3)/(12 + 4)
m = 4/16
m = 1/4
Now that we have the slope, we can use it and either point in point-slope form and solve for the standard form of the equation.
y - y1 = m(x - x1)
y - 1 = 1/4(x - 12)
y - 1 = 1/4x - 3
-1/4x + y - 1 = -3
-1/4x + y = -2
-x + 4y = -8
<1=90=3y-6
3y=96
y=96:3
y=32
9x=6z=90
x=10
z=90:6
z=15
44. BD=AC
2x-1+3y+5=4x-y+1
2x+3y+4=4x-y+1
3y+y+4-1=4x-2x
4y+3=2x
3y+5=2x-1
3y+5=(4y+3)-1
3y+5=4y+2
5-2=4y-3y
y=3
2x=4y+3=4*3+3=15
x=15:2
x=7,5
Answer:
-4/4
Step-by-step explanation:
The slope formula is rise over run. The rise is how much the value is changed on the y-axis, whereas run is the change on the x-axis.
