Question

Graph y=4x-1 using the SLOPE AND Y-INTERCEPT METHOD.
m=??
b=??

Answer 1

y=mx+b is the standard for of slope intercept
m replaces 4 and b relaces -1
y=4x+(-1)
y=4x-1

y-intercept or b is (0,-1)
and the line, the steepness of it has a slope of 4

Answer 2

humm but it says she should use slope intersect to drow

Answer 3

m= tan theta
so theta = tan^-1 4

Answer 4

theta =47.96...
and point of intrsect is (0,-1)

Answer 5

so plot (0,-1)

Answer 6

alrighty so m=4 and b=-1

Answer 7

then plot theta !
theta =75.96

Answer 8

do i need to draw a line through that point ?

Answer 9

yess , see m=4
m= slope = tangent =\( \tan\theta\)

Answer 10

im a bit confused about the formula you're using because i'm in grade 9 and we never learned about tan

Answer 11

like we never used it like..ever

Answer 12

ohh
ok do u know sin , cos ??

Answer 13

nope
none of those

Answer 14

ohh humm then why it asked for
SLOPE AND Y-INTERCEPT METHOD. humm
then use @Zale101 idea ^_^

Answer 15

i think there is a different way to solve it with the slope and y-int method

Answer 16

without the sin and cos and tan thing ...because i don't know about those

Answer 17

yess there is :D

Answer 18

so yea zale probably knows...

Answer 19

try plotting points, it's an easier method to use :)

Answer 20

only find onother point on the line
y=0
x= 1/4

Answer 21

you're finding the line of the equation, right?

Answer 22

i have no idea, like the question on the paper literally matches the question i typed out here

Answer 23

and i'm not the best at this linear relations unit so i don't know where to start
