What is an equation of the line that passes through the points
zubka84 [21]

Answer <u>(assuming it can be in slope-intercept form): </u>

y = x - 5

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula, m = \frac{y_2-y_1}{x_2-x_1}, and substitute the x and y values of the given points into it. Then, solve:

m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1

2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or y-y_1 = m (x-x_1). Substitute m, x_1, and y_1 for real values.

Since m represents the slope, substitute 1 for it. Since x_1 and y_1 represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.

y-1 = 1(x-6)\\y -1 = x-6\\y = x -5

Determine if the data in the table represents a proportional relationship. If yes, give the constant rate.
Flauer [41]

Answer:

no, it is not a proportional relationship.

Step-by-step explanation:

if you divide 315 by 175 you get 1.8

if you multiply 315 by 1.8, you don’t get 420. therefore this is not a proportionally relationship.

hope this helps!
