Answer:

The correct option is 3.

Step-by-step explanation:

If a line passes through to points (x_1,y_1) and (y_1,y_2), then the slope of line is

m=\frac{y_2-y_1}{x_2-x_1}

Given points are (4,-7) and (6,3).

The slope between given points is

m=\frac{3-(-7)}{6-4}

m=\frac{3+7}{2}

On further simplification we get

m=\frac{10}{2}

m=5

Therefore the correct option is 3.

Percy is 8 years older than Ginny. In ten years time he will be three times Ginnys present age. How old is Percy now?
LekaFEV [45]
Now,
G - Ginny's age.
P=G+8, Percy's age.

In 10 years,
G + 10 - Ginny's age in 10 years.
P+10 -  Percy's age in 10 years.

<span> In ten years time Percy (P+10) will be three times Ginnys present age (3G).
P+10=3G

Now we have 2 equations, and we can write a system of equations.

</span>(1)     P=G+8
(2)     P+10=3G  -------> G=(P+10)/3, we need to substitute it into equation 1.

( P=(P+10)/3+8)   /*3
3P=P +10+24
2P = 34
P = 17

Percy is 17 years old now.

Check,
P=17, G=17-8=9
P+10=3G , 17+10=3*9, 27 = 27 True

Find the slope and y- intercept of points (-2,3) and (2,-3)
iren [92.7K]

Answer:

slope = -3/2

y intercept = (0,0)

equation, y = -3/2x+0

Step-by-step explanation:

y2-y1/x2-x1 = -3-3/2--2 = -6/4 = slope = -3/2

y intercept = (0,0)
