Write the slope-intercept form of an equation of the line that passes through
(3, 5) and has a slope of 6.
y = 2x - 6
y = 6x - 13
(y - 5) = 6(x - 3)

(y - 5) = 6(x - 3)
y - 5 = 6x - 18
y = 6x - 18 + 5
y = 6x - 13
Becos question asked for slope-intercept form of an equation, therefore answer is y = 6x - 13.
(y - 5) = 6(x - 3) is only the raw form, format for working.

Remember- the basic slope-intersect equation is y=mx+c
slope is the 'number' (m) with x, hence a slope of 6 means that 6x is in the equation thus eliminating answer 1.
the rest is simply a case of plugging in the values of x=3 and y=5 to determine the y intercept (that is when x=0, what is y? (-13 in this case)
even though answer 3 is also right, it is not in the slope intercept form.

slope intercept form --> y = mx + b the place m is the slope of the line and b is the y intercept. the y intercept is the place the line crosses the y (vertical) axis. i will discover the slope and the y intercept with this equation form to do this difficulty you first have you ever use a various form of equation. that's spoke of as factor slope form. It makes use of a factor on the line, and the slope factor slope form --> (y - y1) = m(x - x1) the place m is the slope and (x1, y1) is a factor on the line (y - 4) = (-a million)(x - (-5)) --> i basically inserted (- 5, 4) for x1 and y1, and m = -a million into the equation. there are assorted negatives on the x ingredient, so shall we take it one step at a time y - 4 = (-a million) ( x + 5) --> now distribute the (-a million) slope y - 4 = - x - 5 --> upload 4 to the two aspects y = - x - a million --> that is slope intercept form. the coefficient of x is the slope and m = -a million the y intercept is the type added or subtracted from x, b = -a million

Sounds like you need to ask questions in your pre-algebra class or use after school tutoring. This is basic middle school math.
Do some back tracking now! Math is something that "builds". If you don't get it now, the whole house will fall down.
What are you going to do when you get to high school? You got 3 years of it there and its based on what you are learning now!
