The function depicted in the table has the following slope-intercept form:
y = -3x + 4
Explain the equation of straight line?
- The formula for a straight line is y=mx+c where c is the slope at which the line intersects the y-axis, often known as the y-intercept, and m is the gradient.
For such equation of every straight line, the slope-intercept form is provided by:
y = mx +c
where:
- The slope of the line is m.
- b is the line's y-intercept.
Choose 2 points from the provided table, such as (2,-2) and (3,-5) and to use the evidence that the slope is, to determine the line's slope.
m = (y2 - y1)/(x2 - x1)
m = -5 + 2 / 3 - 2
m = -3
You can use the point (2,-2) or other point listed in the table along with this relation, to determine the y-intercept b.
b = y1 - mx1
b = (-2) -(-3 + 2)
b = 4
Consequently, is the function represented by the table's slope-intercept form: y -3x + 4.
