Answer:

y = 4x + 9

week 21

Step-by-step explanation:

first I did 37-9 and got 28 I divide that by 7 ( seven weeks) and got 4 so I know the slope is 4.

so to find how many weeks till 93 I did; 93 = 4x + 9. We have to get x by its self so I minus 9 by both sides and got 84 = 4x. So now we divid both sides by 4 to get x by its self and we end up with 21 = x

WILL GIVE BRAINLIEST, 5/5 RATING, AND FAVORITE.

CaHeK987 [17]

Answer:

$y = -\frac{1}{2}x + 2$

Step-by-step explanation:

Assume this is function is a straight line, consider the equation of the straight line: $y=mx + c$

To find the gradient of the equation, we use any two coordinates from the table. $(x_1,y_1) = (6,-1)\\(x_2,y_2) =(2,1)$

$m = \frac{y_1 - y_2}{x_1 - x_2}\\\\m = \frac{1-(-1)}{2-6}\\\\m=\frac{2}{-4} \\\\m=- \frac{1}{2}$

We substitute the value of m in the equation:

$y =mx+c\\y = - \frac{1}{2} x + c\\\\$

To find c, we use the leftover coordinates, (4,0) in the equation above:

$y = -\frac{1}{2}x+c\\\\0 = -\frac{1}{2} \times 4+c\\\\0 = -2 + c\\\\c=2\\\\$

Substitute this value of c in the equation to get the function:

$y = -\frac{1}{2}x + 2$
