Question

Which function passes through the points (2, 15) and (3, 26)?
y = 11x + 7
y = 11x − 7
y = 7x + 11
y = -11x − 7
y = 7x − 11

Answer 1

use this formula\[y=mx+b\]where\[y=vertical~axis\]\[x=horizontal~axis\]\[m=slope\]\[b=y-intercept\]
First find the slope using the given points
Formula for slope is\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 2

ill try

Answer 3

\[Let~say(2,15)=(x_1,y_1)\]\[Let~say(3,26)=(x_2,y_2)\]substitute this value into the slope formula

Answer 4

\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 5

\[m=\frac{ 26-15 }{ 3-2 }\]

Answer 6

\[m=11\]

Answer 7

Now we have the value for x,y and m but we don't have b(y-intercept)

Answer 8

I randomly choose \[(2,15)~as~(x,y)\]

Answer 9

m=11

Answer 10

Now substitute the value into this formula\[y=mx+b\]

Answer 11

what does x equal

Answer 12

\[15=11(2)+b\]\[15=22+b\]

Answer 13

what does b equal to

Answer 14

i randomly choose (2,15) to represent as(x,y)

Answer 15

b=y-intercept

Answer 16

so its what

Answer 17

u have the value for x,y and m...
Now substitute the value into\[y=mx+b\]to find the value of b

Answer 18

The value for x is 2,y is 15 and m=11

Answer 19

No we hv to find the value of b(y-intercept) to form the equation

Answer 20

Now*

Answer 21

\[15=2(11)+b\]\[15=22+b\]Subtract 22 on both sides

Answer 22

\[15-22=22-22+b\]

Answer 23

\[b=15-22\]\[b=?\]solve it @floresf1
