Question

Which equation represents a line that passes through the points (1,1) and (2,7)

Answer 1

Answer: y=6x-5

Explanation:

Explanation:

slope intercept form:y=mx+b

m= slope

b= y-intercept

use the slope formula to get the slope

y2-y1/x2-x1

7-1/2-1

6/1

6 the slope is 6

y=6x+b

plug in values from (1,1) and solve for b

1=6(1)+b

1=6+b

b=-5

y=6x-5
