Estimating line equation and graph

Reference no: EM13123170

Find an equation in slope-intercept form (where possible) for each line.

Through (-2,6), perpendicular to 2x-3y=5

Use slope to show that the square with vertices at (-2, 5) (4,5), (4 -1) and (-2,1) has diagonals that are perpendicular

Graph each equation.

2x-3y= 12

Exercise To achieve the maximum benefit for the heart when exercising, your heart rate (in beats per minute) should be in the target heart rate zone. The lower limit of this zone is found by taking 70% of the different between 220 and your age. The upper limit is found by using 85%.

Find formulas for the upper and lower limits ( u and l) as linear equation involving the age x.
