OpenStudy (asnaseer):

do you know what the equation of a straight line looks like?

OpenStudy (anonymous):

uhh sorry no

OpenStudy (asnaseer):

have you seen an equation of this form?\[y=mx+c\]

OpenStudy (anonymous):

yes but i think you mean b

OpenStudy (asnaseer):

it doesn't matter what symbols you use for the constants. so, look at the equation you have been given - does it resemble the general equation of a straight line y=mx+c?

OpenStudy (anonymous):

yes?

OpenStudy (asnaseer):

correct - the equation is therefore a "linear" equation representing a straight line

OpenStudy (asnaseer):

where instead of 'x' being the variable, you have 't'

OpenStudy (anonymous):

thank you
