A bivariate data set has a line of best fit with equation $y=8.84x$y=8.84x.
Use this equation to calculate the value of $y$y when $x=7.68$x=7.68.
A bivariate data set has a line of best fit with equation $y=-8.71x+6.79$y=−8.71x+6.79.
Predict the value of $y$y when $x=3.49$x=3.49.
A bivariate data set has a line of best fit with equation $y=-0.84x-0.19$y=−0.84x−0.19.
Predict the value of $y$y when $x=-43.15$x=−43.15.
A bivariate data set has a line of best fit with equation $t=4.24s$t=4.24s.
Predict the value of $t$t when $s=3.76$s=3.76.
