Question

Use the linear equation y=−21​x+5

 

a. What is the y- intercept?

 

b. What is the slope of the line?

 

c. Sketch a graph of this equation. You will upload it on the next problem.

Answer 1

the slope is -21 and the y-intercept is (0,5)

you can graph at www dot desmos dot com

the next point is 21 points DOWN and 1 to the right, so (1,-16)

Answer 2

Hello, Quaronna,

y=−21​x+5

 

a. What is the y- intercept? (5, since x=0 at the y intercept)

 

b. What is the slope of the line? (-21, since the format y=mx+b provides the slope as the value of m)

 

c. Sketch a graph of this equation. You will upload it on the next problem. (There isn't room here to add a graph. Try the Desmos free graphing website)
