So as you can see, -3 is the y-intercept. You would make a point on (-3,0) first. Then from the point, you would go up 1 and go right 2 because the slope is a positive 1/2 slope.

In order to graph an equation, you must first need to have a y-intercept to know where your starting point is.

How would I figure out a linear equation with two plot points with fractions? (1/3(6),3) and (1/2(19),-2) are my two plot points

murzikaleks [220]

Answer: $m=\frac{-30}{79},\ y=5.40$

Step-by-step explanation:

Given

Points are $\left(6\frac{1}{3},3\right),\ \left(19\frac{1}{2},-2\right)$

Convert mixed numeral to fraction

$\left(6\frac{1}{3},3\right)\Rightarrow \left(\dfrac{19}{3},3\right)\\\\\left(19\frac{1}{2},-2\right)\Rightarrow \left(\dfrac{39}{2},-2\right)$

Slope of the line is

$\Rightarrow m=\dfrac{3-(-2)}{\dfrac{19}{3}-\dfrac{39}{2}}\\\\\Rightarrow m=\dfrac{5}{\dfrac{38-117}{6}}\\\\\Rightarrow m=\dfrac{-30}{79}$

Equation of line

$\Rightarrow \dfrac{y-3}{x-\dfrac{19}{3}}=\dfrac{-30}{79}\\\\\text{for y-intercept, put x=0}\\\\\Rightarrow \dfrac{y-3}{0-\dfrac{19}{3}}=\dfrac{-30}{79}\\\\\Rightarrow y-3=\dfrac{190}{79}\\\\\Rightarrow y=3+2.40\\\Rightarrow y=5.40$

Hey Guys! PLEASE HELP QUICK! I'M OFFERING 15PTS AND THE BRAINLIEST ANSWER. PLEASE , PLEASE , PLEASE FOLLOW THE DIRECTIONS AND SH

A. Your variable is the number of miles that Steve runs (which I'll label as S; Kevin's distance is K)

b. The expression for Kevin would be:
S+4 = K ---> Why? Because it says that Kevin ran 4 more miles than Steve did. So, whatever value S is, K is always 4 more than that.

The expression for Steve would just be: S = S

c. The equation is: 4+S+S = 26. Why? Because since the two ran a total of 26 miles together, K+S = 26. But, we already figured out that K = S+4 (see b.). So, we can substitute 4+S for K into K+S=26 to get 4+S+S = 26.

d. Solving it:
4+S+S = 26 ---> 4+2S = 26 ---> 2S = 22 ---> S = 11
Solution: Steve ran 11 miles.

e. Checking: plug in 11 as S
4+2(11) = 26 ---> 4+22 = 26 ---> 26 = 26
And...it's in the domain they give you.

Final Answer: 11 miles
