A two step equation for what.<span />
Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
a)
h(t) , namely "h" variable is being represented in terms of "t".
h = dependent variable, depends on the value of "t", output.
t = independent variable, takes on values freely, input.
b)

c)

after 2 seconds, the ball is 11 meters high up.
The answer would be infinite number of solutions
