How do you find the slope and y intercept for #4x+5y=-10#?

Answer 1

Hazel Anglin

Given #4x+5y = -10#

we can re-arrange this as #y = -4/5x + "some constant"# So the slope is #(-4/5)#

The y-intercept is the value of #y# when #x=0# #4(0) + 5y = -10# #rarr y = -2# The y-intercept is #(-2)#

To find the slope and y-intercept for the equation 4x + 5y = -10, rearrange the equation into slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept. To do this, isolate y by subtracting 4x from both sides, which gives you 5y = -4x - 10. Then, divide both sides by 5 to solve for y, yielding y = -4/5x - 2. Therefore, the slope is -4/5 and the y-intercept is -2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
