Question

A line goes through the points (0, 3) and (1, 7). Find the slope, and then use the point that is the y- intercept to write the equation of the line.​

Answer 1

Slope = 4

y = 4x + 3

Explanation:

y2 - y1

x2 - x1

= 4

Answer 2

y = 4x + 3

Explanation:

slope m = (7 - 3)/(1 - 0) = 4/1 = 4

y = mx + b

given y = 3, x = 0, m = 4

3 = 4(0) + b

b = 3

=> y = 4x + 3
