Check my answer?
Question: Write an equation in slopeintercept form for the line that passes through (3, 7) and (7, 4).
My answer: Okay so first we use the slope formula to find the slope of the line. y2  y1/ x2  x1 = 4  7/7  3 =  3/4. So  3/4 is the slope so now we can use the point slope form. y  y1 = m (x  x1) = y  7 =  3/4( x  3) = y  7 =  3/4x + 2.25, now we add seven to both sides. y  7 + 7 =  3/4x + 2.25 + 7 = y =  3/4x + 9.25.

Best ResponseYou've already chosen the best response.1I have to do it myself to check it. Find slope. \[m =\frac{ y2  y2 }{ x2  x1 } = \frac{ 4  7 }{ 7  3 } = \frac{ 3 }{ 4 }\] So you got the slope right, 3/4. (3, 7) and slope 3/4 PointSlope form is y  y1 = m (x  x1). y  7 = 3/4(x  3) Change to SlopeIntercept form. Distribute. Put into decimal form if its easier. y  7 = 3/4x + 9/4 or y  7 = 3/4x + 2.25 Add 7. y = 3/4x + 9.25 If I didn't make any mistakes, I think you are right!
