Answer: explain how to graph an equation in slope-intercept form.
Step-by-step explanation: To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.
To find the line, you need to use the point-slope formula because you're given both the slope and a point.
y - y₁ = m(x - x₁)
m = -2/5
x₁ = 10
y₁ = 3
y - 3 = -2/5(x - 10)
y - 3 = -2/5x + 4
y = -2/5x + 1
y = -2/5x + 1 is the line.
