If somebody could please help me with this and answer it I would be really grateful! Im stuck :(
Write an equation in slope-intercept form for the line that satisfies the following condition. passes through (13, 9) and (30, 26)
Tutors, please sign in to answer this question.
We know two points on the line: (13, 9) and (30, 26).
We know that slope intercept form is y = mx + b
The slope, m, is given by (26 - 9)/ 30 - 13) = (17)/(17) = 1
y = x + b
All we have to do now is to figure out the y-intercept, b
b = y - x
b = 9 - 13 = -4
Note that we would get the same result if we had used
b = 26 - 30 = -4
So the equation of the line is y = x - 4
