How do you graph #y=x-10#?
3 Answers
graph{y = x-10 [-10, 10, -5, 5]}
Explanation:
The gradient is the coefficient of the x in the equation, so
The c value is the y intercept, which is
Therefore it's a line going through
Start at (0 -10) make a point go up one and to the right 1 make a second point at ( 1 -9) connect the two points.
Explanation:
The equation is the y intercept form
where
m = the slope think mountain ski slope.
b = the y intercept think beginning.
m in this equation is 1/1
b in this equation is -10
so start at b the y intercept of ( 0, -10)
This is the first point.
Then use the slope y =1 so go up 1
x= 1 so one to the right
The second point is then ( 1,-9)
Graph the two points and connect them to form the line.
Explanation:
#"one way is to find the intercepts, that is where the graph"#
#"crosses the x and y axes"
#• " let x = 0, in the equation for y-intercept"#
#• " let y = 0, in the equation for x-intercept"#
#x=0rArry=0-10=-10larrcolor(red)"y-intercept"#
#y=0rArrx-10=0rArrx=10larrcolor(red)"x-intercept"#
#"plot the points "(0,10)" and "(10,0)#
#"draw a straight line through them for graph"#
graph{(y-x+10)((x-0)^2+(y+10)^2-0.04)((x-10)^2+(y-0)^2-0.04)=0 [-20, 20, -10, 10]}
