Question

PLEASE HELP! SOLVE USING: y=mx+b
1. Using the slope-intercept form of a line, find the equation of the line with slope 3/2 and
y-intercept –2. Then graph the line on the grid provided and explain how you determined your graph.

Answer 1

this question is asking if you can remember what
slope-intercept form of a line
means
they give you the formula y=mx+b
which is a big hint.

what does the "m" stand for in the formula ?

Answer 2

mx= 3/2

Answer 3

m is the slope

for your problem , the slope is 3/2 so m=3/2
just m= 3/2
the x is the "variable"

so far you have
y= 3/2 x + b

Answer 4

in slope-intercept form y= mx+b
you have two things (other than the "x") : slope and intercept
you know that m is the slope. any guess what b is ?

Answer 5

-2

Answer 6

so using b (the intercept) is -2, your equation
is
y= (3/2) x - 2

Answer 7

to graph it, you need to find two points on the line. plot the two points, and draw a line through the points

Answer 8

Thank you :)
