Question

Use y=mx+b form to write the equation of a line with a slope -3 and y intercept 0.

Answer 1

slope = m = -3
y-intercept = b = 0
Just insert those values in y = mx + b and simplify.

Answer 2

Whats X?

Answer 3

y ans x are part of the equation and stay there.

Answer 4

Can you explain it better please?

Answer 5

x is the value of x in the ordered pair (x,y). Slope intercept form is the relationship between X and y.

Answer 6

y = mx + b with m = -3 and b = 0
y = (-3)x + 0
y = -3x

Answer 7

So saying y=3x means that for any x value, the corresponding y value is 3times that x value.

Answer 8

Oh okay
