Question

The points (1, 10) and (0, 2) fall on a particular line. What is its equation in slope-

intercept form?
0) Write your answer using integers, proper fractions, and improper fractions in simplest
form.
y = x +

Answer 1

y=3x+2

Explanation:

Answer 2

y = 8x + 2

Explanation:

Let the equation of the line is,

y = mx + b

Here, m = slope of the line

b = y-intercept

Since, slope of a line passing through two points
`(x_1,y_1)` and
`(x_2,y_2)` is,

m =
`(y_2-y_1)/(x_2-x_1)`

By this formula, slope of a line passing through (1, 10) and (0, 2) will be,

m =
`(10-2)/(1-0)`

m = 8

Equation of the line will be,

y = 8x + b

Since, this line passes through (0, 2),

2 = 8(0) + b

b = 2

Therefore, equation of the line will be,

y = 8x + 2
