Start by using the Slope Formula to find the slope.
y=1/2x+5
An equation in slope-intercept form follows a specific format.
y= mx+ b
For an equation in this form, m is the slope and b is the y-intercept. We can calculate the slope by substituting two points from the given table into the Slope Formula. Let's choose the points (-2,4) and (0,5).
Substitute ( -2,4) & ( 0,5)
A slope of 12 means that for every 2 horizontal steps in the positive direction, we take 1 vertical step in the negative direction. Now that we know the slope, we can write a partial version of the equation. y= 1/2 x+ b To complete the equation, we also need to determine the y-intercept b. Since we know that the given points will satisfy the equation, we can substitute one of them into the equation to solve for b. Let's use ( 0, 5).
x= 0, y= 5
Zero Property of Multiplication
Identity Property of Addition
Rearrange equation
A y-intercept of 5 means that the line crosses the y-axis at the point (0, 5). We can now complete the equation. y= 1/2x+ 5
