Question

please help me

Answer 1

y2-y1 / x2-x1 this will allow to find the slope of the graph

Answer 2

then use this y=mx+b to find your y - intercept of the graph

Answer 3

98-130 / (90-50)

Answer 4

y = -4/5x + 170

Answer 5

how do I find the rate of change in the target heart rate

Answer 6

The rate of change in the target heart rate is
​beats/minute
per year of age
how do I find this @Scooby6363 @latinC

Answer 7

Rate is - 4/5 beats/ min per year

Answer 8

-(4/5) is your slope and the X value is your age
so
Target = -(4/5)*age+170

Answer 9

Target is your (Y) value and age is your (X) value

Answer 10

The target heart rate of a person age 70 is ___ bpm

Answer 11

@latinC how do I find the target heart rate of a person age 70

Answer 12

@pphalke Since the slope-intercept formula is (-4/5)x + 170, substitute 40 years of age for x.

(-4/5)(40 years of age) + 170 = 138 beats/minute
