finding a equation in slope-intercept form. Through (-9, 2.5) and (-5, 4.5)
Answered by Laly
Y= -1/7X + 1.2
Answered by Damon
(Y2-Y1)/(X2-X1) = slope

(4.5-2.5) / (-5+9) = slope call it m
then
(y-Y1)/(x-X1) = that same slope, m
so finally

y = Y1 + m (x-X1)

Answered by Maria
Is this correct? Ans. y=2x+20.5
