Question

Slope is -3 and a y-intercept is 7

Answer 1

Answer:

y = -3x + 7

Step-by-step explanation:

Write the equation of a line using slope-intercept form which uses the equation y = mx + b.

This is what each letter (variable) means:

"m" is the slope of the line (how steep it is).

"b" is the y-intercept (when the line hits the y-axis).

"x" and "y", when the equation is still balanced, is a point on the line.

To write the equation, we need the slope "m" and the y-intercept "b", which is given in the question.

Substitute the numbers into the equation y = mx + b.

y = -3x + 7
