Okay so the equation y two - y one divided by x two - x one will solve this.
what y two means is that you need to plug that in for the second y value. since fractions are in x, y form and you need to start with the second y value,and it would be 3 and following that same idea with y but with the first pair of coordinates it would be 2. so we have done half of this so far by getting 3-2 but we still need to do the same thing we just did BUT for THE X COORDINATES. remember to put the SECOND x coordinate first like we did with the y coordinate. so this portion should be -4 - (-1) all together. never forget if a number has a negative sign! so now the final equation is 3-2 divided by -4 - -1. three minus 2 is 1 and -4 - -1 is -3. now divide your separate answers by each other which is 2 divided by -3 which is -0.666..... you can round that answer or just keep it in fraction form of -2/3 if you’d like.

y=3/4x
-4=3/4 (7)+b
-4=21/4+b
-4-21/4= -37/4
21/4-21/4=0
y=3/4x-37/4

Answer:
F
Step-by-step explanation:
If the circle is tangent to the x-axis at 4, the center lies on the line x=4.
If the circle is tangent to the y-axis at 4, the center lies on the line y=4.
If the center of the circle is (x, y) = (4, 4) and it is tangent to the axes, then the radius is 4.
The standard-form equation of the circle centered at (h, k) with radius r is ...
(x -h)² +(y -k)² = r²
For the values (h, k) = (4, 4) and r = 4, the equation is ...
(x -4)² +(y -4)² = 16 . . . . . . matches choice F
Answer:
Step-by-step explanation:
Because the function is a product, the zeros will occur when any term is equal to zero. For
(x-1)(x+3)(2x+1) the value will be zero when x=1,-3, or -1/2 so the points are
(-3,0), (-1/2,0), and (1,0)
