Question

PLEASE HELP!!! Write the equation of the line that passes through (−3, 5) and (2, 10) in slope-intercept form.

Answer 1

slope formula

\(\tt{\dfrac{y_2-y_1}{x_2-x_1}}\)

Answer 2

\(\tt{x_1=-3\\y_1=5\\x_2=2\\y_2=10}\)

Answer 3

The choices are:
y = x + 8
y = x − 8
y = −5x − 10
y = −5x + 20

Answer 4

ok so let's find the slope

\(\tt{\dfrac{10-5}{2-(-3)}=\dfrac{5}{5}=1}\)

Answer 5

so slope is x

Answer 6

\(\tt{y=x+b}\)
we need to find the y-intercept

Answer 7

we can use any of the ordered pairs.

Answer 8

so (-3, 5) would be 5 = -3 + b ?

Answer 9

yes so solve for b

Answer 10

is it b = 8 ?

Answer 11

yup

Answer 12

so slope is 1x or just x
y-intercept is 8

Answer 13

that makes the equation
\(\tt{y=x+8}\)

Answer 14

oh, okay! thank you

Answer 15

yw :]
