Question

What is the equation of the line that passes through the point (3, 2) and has a slope of 4?

y = 4x - 1

y = 4x - 5

y = 4x - 10

y = 4x + 1

Answer 1

Also please tel me how to solve this. Thanks!

Answer 2

the equation of straight line :
y = mx + b
with m=slope, b=constant

Answer 3

u just subtitute the m=4 and and the coordinat point (x,y)=(3,2) to formula above

Answer 4

I still can't figure it out.

Answer 5

y = mx + b
first, put m=4, it means
y = 4x + b, right ?

Answer 6

r u there?

Answer 7

then to find the value of b, subtitute the point (3,2) to equation above :
y = 4x + b
2 = 4*3 + b
2 = 12 + b or
b = 2 - 12
b = -10
so, y = 4x + b
y = 4x -10

Answer 8

I am here.

Answer 9

So the slope is always M? And in this case M = 4? Correct?

Answer 10

I get it, you explained it very well. Thanks!
