Question

Which is the equation of a line that passes through the point (3, -4) and has a slope of 2.
Select one:
a. y = 2x - 10
b. y = 2x - 2
c. y = 2x - 4
d. y = 2x - 11

Answer 1

well the slope intercept form of the line is

y = mx + b

m = slope and b = y-intercept

you know m = 2

so the equation is

y = 2x + b

to find b, substitute the point x = 3 and y = -4

hope it helps

Answer 2

first find b from the above explanation of @campbell_st

Answer 3

@campbell_st what do you mean plug it in for x? like y=2(3)+b is y=6+b or y=8+b what do i do after

Answer 4

almost y = -4 and x = 3 so its

\[-4 = 2 \times 3 + b\]

now solve for b

Answer 5

first find b
like this
y=2x+b..........eq#1

-4 = 2(3) + b

b=-10
now put b=-10 into eq#1
and you will get
y= 2x-10

Answer 6

there you go... someone always gives the answer

Answer 7

@campbell_st sorry if you dont like it
but medal is your

Answer 8

@AWillie98 did you get it how we solve it ?

Answer 9

i didn't want @Haseeb96 to give me the answer @campbell_st ill never learn it that way
