Slope
if the slope of a line is 3 and it passes through the point (1,2),what is the y-coordinate of the point when x=4?
y=11
what is the y-intercept of the line with the equation y=4x-2?
-2
solve for x, 2x+3=11
subtract 3 from both sides 2x=8 then divide by 2 ,x=4
solve 2x+y=7, x-y=1
x=8/3 and y =5/3
what is graphing?
graphing is a visual representation of mathematical concepts, equations ,or data on a coordinate plane
What is the definition of slope?
can a vertical line have a y-intercept?
noo
solve for x , 3x/4=6
multiply both sides by 3:3x=24 then divide by 3:x=8
solve x+2y=4,3x-y=5
the solution is x=2 and y =1
what is the purpose of the x-axis and y-axis on a graph
the x-axis represents the horizontal component the y-axis represents the vertical components of a graph
what is the slope of a line that passes through the points (2,3) and (4,7)?
the slope that passes through (2.3) and (4,7) is 7-3/ (4-2)=4 or 2=2
what is the y-Intercept of the line with the equation y=3x=5?
y-Intercept is 5, the value of y when x is 0
solve for y ,5y - 7=18
add 7 to both sides,5y=25 then divide by 5 ,y=5
solve 4x-y=9, 2x+3y=1
the solution is x=2 and y=-1
what is the x-axis
the horizontal axis on a graph
what is the slope of a horizontal line?
the slope is 0
if the line passes through the point (0,-3) what is the y-intercept?
the y-intercept is -3
solve for y, 7y+2=30
y=4
solve x + y=7 ,2x +3y=14
the solution is x=3 and y =4
what is the y-axis
the vertical line on the graph
what is the slope of a vertical line?
undefined
what is the y-intercept of the line with the equation y=-2x+7?
the y-intercept would be 7
solve for c,x/2 +5=9
x=8
what is a system of equation?
what does it mean if two lines intersect
it means they share a common point, which is the solution to both equations
