How do you find the slope and intercept of #3x + y = -4#?

Answer 1

Savannah Anderson

Slope #m=-3#, &, Y-intercept #c=-4#.

The slope-intercept form of a line is # : y=mx+c#, where, #m# is slope and #c# is Y-intercept of the line..

The given eqn. is, # : y=-3x-4#

Clearly, the Slope #m=-3#, &, Y-intercept #c=-4#.

slope = -3 , y-intercept = -4

The equation of a line in #color(blue)"slope-intercept form"# is

#color(red)(|bar(ul(color(white)(a/a)color(black)(y=mx+b)color(white)(a/a)|)))# where m represents the slope and b. the y-intercept.

The equation's advantage is that m and b can be "easily" extracted in this format.

Calculate 3x + y = -4 using this formula.

deduct 3x from each side.

#cancel(3x)+y-cancel(3x)=-3x-4rArry=-3x-4#

Now y = -3x - 4 is in #color(blue)"slope-intercept form"#

Thus, y-intercept = -4 and slope = -3

To find the slope-intercept form (y = mx + b) of the equation 3x + y = -4, where m is the slope and b is the y-intercept, you need to solve for y:

3x + y = -4 y = -3x - 4

So, the slope of the equation is -3 and the y-intercept is -4.

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.
