Exercise 10 Page 273

Substitute the slope and y-intercept into the slope-intercept form.

Slope-Intercept Form: y=3x+5
Graph:

Practice makes perfect

Lines written in slope-intercept form follow a certain format. y= mx+ b In this form, m is the slope and b is the y-intercept. By substituting m= 3 and b= 5 into this equation, we can write the line's slope-intercept form equation.

y= 3x+ 5 To find another point through which the graph passes, we will use the slope. If we rewrite the slope m= 3 as a fraction, it becomes 31. m=rise/run=3/1 Since we know that the equation intercepts the y-axis at (0, 5), we will travel 1 step to the right and 3 steps up from there. Finally, we draw a line that passes through the points.
