8 0

7+2y=8
3x-2y=0

7+2y=8
y=8/3

3x-2(8/3)=0
3x-16/3=0
+16/3 +16/3
3x=16/3
/3 /3
x=16/9

$\frac{y\ miles}{x\ minutes}=\frac{4\ miles}{28\ minutes}\ \ |cross\ multiply\\\\28y=4x\ \ \ \ |divide\ both\ sides\ by\ 28\\\\\boxed{y=\frac{4}{28}x\Rightarrow y=\frac{1}{7}x}$

How can you use the point-slope form of a line when only given two points?

pshichka [43]

Answer:

See below

Step-by-step explanation:

Point -slope form is:

y - y1 = m(x - x1)

By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.

How to find the slope?

Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2

Use the formula:

m = (y2-y1)/(x2-x1)

Example:

m = -5, and one of the points has coordinates (9, 2) then point-slope form is:

y - 2 = -5(x - 9)
