A line passes through the point (-4, -8) and has a slope of 5/2 write an equation in slope intercept form for this line
Tju [1.3M]

Answer:

y = 5x/2 + 2

Step-by-step explanation:

We know the equation for slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Since we have the coordinates of one point on this line and the slope, we can substitute that in and find b first:

y = mx + b

-8 = 5/2(-4) + b

-8 = -10 + b

b = 2

So we can use the slope and this y intercept we found to plug back into the equation:

y = mx + b

y = 5x/2 + 2

It appears that your answer contains either a link or inappropriate words. Please correct and submit again!

Answer:

See below. The answer is incomplete, I couldn't post it.

Step-by-step explanation:

Considering a function f, it is said to be discontinuous when it has a hole or breaks, it means places where f(x) cannot be evaluated. For example, when the denominator equals to 0, it is not defined.
