"Has an x-intercept of 6 and a y-intercept of 3." Could someone write that equation in slope-intercept, point slope, or standard form?

That's slope-intercept form

Thank you so much! Could you show me how you got that?

sure
slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
with the x intercept and the y intercept I got a slope of 1/2
then I just inserted it in and got y = 1/2x + 3 since there's a y-intercept of 3

do you want me to explain slope?

Sure, I'm not sure how to get the slope.

ok the slope is change of y / change of x
so the x-intercept is (6,0)
and the y-intercept is (0,3)
so 3-0/0-6 = 3/-6 = 1/-2

BTW change it to y = 1/-2x + 3 I forgot it in the original answer sorry

\[y = \frac{ 1 }{-2 }x + 3?\]
