Question

Write the slope-intercept (y = mx + b) form of the equation from the information given.

The line goes through the points (1/2, 3/2) and (-1/4, 5/4)

@atreyu6s3x6 and @AbdullahM Can y'all help me? I can't figure this one out at all

Answer 1

first we need to find the lope (m).

to do this use the slope formula \[\frac{ y_1-y_2 }{ x_1-x_2 }\]

Answer 2

round two!!!!

okay this is basically the same thing we did on the other problem

Answer 3

substitute values:

(3/2-5/4)/(1/2-(-1/4))=(1/4)/(3/4)=1/4*4/3=1/3

thus slope is 1/3, thus m=1/3

Answer 4

So the slope is 1/3?

Answer 5

now chose any point and substitute it into the equation with slope to find y intercept:

3/2=1/3*1/2+b
3/2=1/6+b
9/6-1/6=b
8/6=b
b=4/3

thus y intercept is 4/3.

now knowing that the slope is 1/3 and y intercept is 4/3 we can substitute this into our equation:

y=1/3x+4/3

Answer 6

everything is correct
