Answer:
1. y=6x-22
Step-by-step explanation:
point-slope form equation : y=mx+b
1. (3, -4) m=6
Sub the numbers is
y=-4 / x=3 / m = 6
-4=6*3+b
-4=18+b
b=-22
So your equation would be y=6x-22
2. (4, 2) m=-5/3
sub the numbers into the equation
y=2 / x=4 / m= 5/3
2=4*5/3+b
2=20/3+b
b=8 2/3
so the equation would be
y=-5/3x+8 2/3
3. (0,2) m=4/5
sub the numbers into the equation
2=0*4/5+b
b=2
so the equation would be
y=4/5x+2
4. (-2, -7) -3/2
sub the numbers into the equation
-7=-3/2*-2+b
b=-10
so the equation would be
y= 3/2x-10
5. (4,0) 1
sub the numbers into the equation
0=1*4+b
b=-4
so the equation would be
y=x-4
6. (5,-8) -3
sub the numbers into the equation
-8=5*-3+b
-8=-15+b
b=7
so the equation would be
y=-3x+7
7. (-5, 2) 0
sub the numbers into the equation
2=-5*0+b
b=2
so the equation would be
y=2
8. (1, -8) -1/5
sub the numbers in
-8=1*-1/5+b
b= 7 3/5
so the equation would be
y=-1/5x + 7 3/5
9. (-6,1) 2/3
sub the number in
1=2/3*6+b
b=-3
so the equation would be
y=2/3x-3
Answer:
y= 5x -2 or y-13 = 5 (x-3)
Step-by-step explanation:
The first one is slope-intercept form, the second is point-slope form
<span>the probability of drawing a marble that is not red from the bag is 66%</span>
L=7+W
area=30=LW
so subsitute 7+W for length
30=(7+W)(W)
30=W²+7W
minus 30 both sides
0=W²+7W-30
factor
what 2 numbers multiply to get -30 and add to get 7
-3 and 10
0=(W-3)(W+10)
set to zero
0=W-3
3=W
0=W+10
-10=W
false, can't have a negative width
width=3in
L=7+W
L=7+3
L=10
the length is 10in
the width is 3in
The measure of angle GXI is 80
