Slope intercept form is y = mx + b...ur slope will be in the m position and ur y int will be in the b position
examples : slope = 2 , (1,3)....x = 1 and y = 3
y = mx + b slope(m) = 2 (1,3)...x = 1 and y = 3 now we sub and find b, the y int 3 = 2(1) + b 3 = 2 + b 3 - 2 = b 1 = b
so in slope intercept form, ur equation is : y = 2x + 1 ================ another example : slope = 3 , (-2,-4)
y = mx + b slope(m) = 3 (-2,-4)...x = -2 and y = -4 now sub and find b, the y int -4 = 3(-2) + b -4 = - 6 + b -4 + 6 = b 2 = b so ur equation is : y = 3x + 2
