Question

A line has a slope of -1.5 and a y-intercept of (0,3). What is the value of y when x = 6 ?

Answer 1

y = mx + b
where m is the slope -1.5
and b is the y-intercept (0,3)
plug those in and create your linear equation. Afterwards plug in x=6 to find y.

Answer 2

-1.5 * 6 = 9 + 3 =12
y = 12?

Answer 3

@Zale101 ?

Answer 4

Wait, it would be -9. So -9 + 3 = -6

Answer 5

y = mx + b
y = (-1.5)x + (3) <-- your linear equation
y=(-1.5)(6)+3 <--- plug in x=6 and solve for y

Answer 6

y = -6 ?

Answer 7

yes

Answer 8

thanks!

Answer 9

You're welcome :)
