Best ResponseYou've already chosen the best response.2Slopeintercept form: y = mx+b, where m is the slope of the line and b is the yintercept. So use the equation above to find your answer just plug in the values given.

Best ResponseYou've already chosen the best response.0I'm sorry! Is this your question: write an equation in slope intercept form of the line that contains (1,7) and (3,9) ? I didn't notice you had edited your original question!

Best ResponseYou've already chosen the best response.0First, find the slope. (1,7) and (3,9) \[m = \frac{ y2  y1 }{ x2  x }\]\[m = \frac{ 9  7 }{ 3  (1) } = \frac{ 9  7}{ 3+1 } = \frac{ 16 }{ 4 }= 4\]Slope is 4  You have a point (1, 7) and the slope(4) so use the PointSlope formula. y  y1 = m(x  x1) y  7 = 4(x  (1)) y  7 = 4(x + 1) \[Distrbute\]y  7 = 4x  4 \[Add \quad 7\]y = 4x + 3
