Question

A line has a slope of 1 and passes through the point (5,8). What is its equation in slope-intercept form? QUICKLY PLEASE+ BRAINIY AND 5 STAR

​

Answer 1

y = x+3

Explanation:

If the slope is 1, thus y = 1(x) + b.

Substituting x = 5, y = 8 into the formula,

8 = 5 + b.

b = 3

Thus, the formula is y = x + 3.

Answer 2

y = x + 3

Explanation:

The slope intercept form is:

y = ax + b

where the a is the slope and b is the y intercept.

We know that the slope is 1:

y = 1x + b

and then the point:

8 = 1(5)+b

We can solve this:

8 = 5 + b

8 - 5 = b

3 = b.

Then we can plug b back in for the slope intercept form:

y = x + 3

Hope that helps!
