Determine the slope and the y-intercept of the line represented by the equation y= -7/3×+3 slope: 7/9 ;y-intercept: 3 slope: 9/7
Mademuasel [1]

Answer:

slope ⟹ \:  -  \frac{7}{9}  \\ y  \:  intercept⟹ \: 3

Step-by-step explanation:

The standard form of this equation is

y = mx + c \\

m stands for the gradient or the slope, and c represents the y-intercept

y = mx + c \\ y =  -  \frac{7}{9} x + 3 \\ m =  -  \frac{7}{9}  \:  \\ and \:   \\  \: y \: intercept \:  = 3
